NBN FTTP vs FTTB https://alcatron.net/2018/11/20/nbn-fttp-vs-fttb/ https://alcatron.net/2018/11/20/nbn-fttp-vs-fttb/#respond Tue, 20 Nov 2018 00:26:05 +0000 http://www.alcatron.net/?p=920 The Australian National Broadband network, is being rolled out full steam ahead, here are some of the differences between FTTB vs FTTP rollout to a building.
FTTB is Fibre to the Basement, and FTTP is Fibre to the Premises, these two terms sound very similar, but are quite different in the way they operate, and may be confusing for you.

To summarize this, here it what it exactly means:

FTTB
Physical – Powered DSLAM device that sits in the basement of the building. This DSLAM works off VDSL2 to the end user.
Speed Residential – It has a maximum speed of UP TO TC4 100/40  – Depending on the copper length from DSLAM to end user as signal will attenuate on longer distance and provide less speed
Speed Business Grade – It has an estimated Traffic Class 2 – TC2 20/20 (Synchronous)

FTTP

Physical – Fibre direct to your premise with a Network Termination Device (NTD) that you connect up to 4 data connections and 2 analogue telephone ports. You can order battery backup on the NTD as well

Redundancy and Flexibility – 4 data ports – meaning up to 4 services from up to 4 carriers can be connected – this can allow for carrier redundancy and also if you wanted to separate your networks on each port using one for each – eg. corporate data/guest wifi/3rd party businesses on each port.

Speed – It has a maximum Speed of TC2 100/100 – Business Grade Service – with high download and upload speeds for corporate application data/video conference/VOIP with guaranteed performance parameters around jitter and lag that many enterprise applications require to run efficiently and without delays, time outs and buffering.

Speed –  It also has a range of residential grade (Traffic Class 4 – TC4) speed tiers you can order up to a maximum of TC4 1000/400.

 Main benefits of FTTP over FTTB are:

  • Significantly faster speeds – Enterprise Class speeds of TC2 100/100 which ensures guaranteed performance for critical systems
  • Smoother connection experience with a fibre connection compared to copper based FTTB
  • Battery Backup on the nbn edge device is available in the event of a power outage

At the moment NBN is delivering FTTB in most places in large apartment buildings, hospitals, etc , but the business can choose for a FTTP delivery instead if they wish to, however this will come with an extra cost which NBN can provide a quote for.

Allow incoming VPN Users Local LAN access + Internet on Cisco ASA https://alcatron.net/2018/07/09/tunnel-local-lan-access-internet-via-vpn-on-cisco-asa/ https://alcatron.net/2018/07/09/tunnel-local-lan-access-internet-via-vpn-on-cisco-asa/#comments Mon, 09 Jul 2018 12:03:31 +0000 http://www.alcatron.net/?p=895 I wanted to try do something on my Cisco ASA to setup incoming IKEV/IPsec/L2TP VPN to allow access to the local LAN and also the internet connection which the ASA Uses. So when a client connects to the VPN, they can access the local lan, as well as the internet connection that sits off from the ASA.

In order to set this up, we have to have something like this going, all performed in enable configuration mode.

  1. Define your VPN Pool of addresses eg
    ip local pool VPNUsers 192.168.20.1-192.168.20.30 mask 255.255.255.224
  2. Relax the security rules between the interfaces a bit
    same-security-traffic permit intra-interface
  3. Create an object for example like VPN, then NAT the outside interface to the outside, this allows routing of internet from VPN to the ASA using the ASA’s ISP connection on outside
    object network VPN
       subnet 192.168.20.0 255.255.255.224
       nat (outside,outside) dynamic interface 
  4. Allow VPN Interface “Hairpin” on same interface and access to local LAN/Internet resources
    nat (outside,inside) source static VPN VPN
    
  5. Create a VPN Clients Out ACL, to allow the VPN Client subnet, access from its subnet to any IP address on the outside (in our case the local LANs or internet)
    access-list VPN_CLIENTS_OUT extended permit ip object VPN any
  6. Modify the group policy tunnel attributes attached to your tunnel. In my scenario below VPN Clients will use the Cloudflare DNS, utilise the correct ACL for access, allowed IKEV or L2TP protocols, all traffic will be tunneled and no split traffic permitted on client, and the IP address pool will be utilised from our VPNUsers pool

    group-policy yourtunnel attributes
      dns-server value 1.1.1.1 
      vpn-filter value VPN_CLIENTS_OUT
      vpn-tunnel-protocol ikev1 l2tp-ipsec 
      split-tunnel-policy tunnelall
      address-pools value VPNUsers
  7. Once the above is implemented, the VPN clients will have access to the Local LAN, and to the Internet connected to the ASA. The above configuration does not take into consideration the complete VPN Tunnel setup, this additional configuration assumes you already have an existing complete tunnel setup.

    This took me some time to get working, so I wanted to put some of my research on my blog incase anyone wishes to do the same, feedback welcome 🙂

ACCC Monitoring broadband performance https://alcatron.net/2018/04/29/accc-monitoring-broadband-performance/ https://alcatron.net/2018/04/29/accc-monitoring-broadband-performance/#respond Sun, 29 Apr 2018 10:42:01 +0000 http://www.alcatron.net/?p=882 The Australian Federal Government announced a scheme to bring ISPs to account so that they are providing and provisioning enough bandwidth on the NBN and they have setup a broadband monitoring program. I decided to be part of this program, and I have received a monitoring box from Sam Knows One. SamKnows One is a platform that contains a comprehensive set of tools that allows you to measure and analyse your broadband performance, across fixed, mobile and Wi-Fi services. It has a web-based portal that you can use to analyse your measurement results.

The box records the data, and then ACCC have access to this data as well to determine how well the carrier is giving you the performance.

These are some photos how it looks like, and the web portal how performance is measured etc, its quite useful, so you can keep track of your performance. In my scenario my Telstra 100/40 NBN Fibre service is being measured.

If you would like more info on this program see https://www.accc.gov.au/consumers/internet-phone/monitoring-broadband-performance

Cisco VPN Client on Windows 10 https://alcatron.net/2018/02/18/cisco-vpn-client-on-windows-10/ https://alcatron.net/2018/02/18/cisco-vpn-client-on-windows-10/#respond Sun, 18 Feb 2018 03:14:03 +0000 http://www.alcatron.net/?p=876 Need to use the Cisco VPN Client in Windows 10? There is a way to get it working on Windows 10… but it just involves a few additional steps..

  1. Run the installer vpnclient-winx64-msi-5.0.07.0440-k9.exe
  2. Install dneupdate64.msi
  3. Edit the registryWith Regedit open, locate the registry key HKEY_LOCAL_MACHINE and click the drop-down icon. Then do this again for System, CurrentControlSet, Services, and finally, CVirtA.
    From there, double-click DisplayName and change the value data to “Cisco Systems VPN Adapter” (without quotes) if you’re using the x86 32-bit version of the software or “Cisco Systems VPN Adapter for 64-bit Windows” (again, without quotes) if you’re on the 64-bit version.

    For reference, the original value data entry should look like this:
    32-bit (x86): @oem8.ifn,%CVirtA_Desc%;Cisco Systems VPN Adapter
    64-bit (x64): @oem8.ifn,%CVirtA_Desc%;Cisco Systems VPN Adapter for 64-bit Windows

    Once you’ve made the appropriate changes to your registry, restart Windows and you’re done.

Hope this has helped you install it on Windows 10 🙂

Apple IOS 11 & Cisco Wireless – Fast Transition (FT) https://alcatron.net/2017/12/13/apple-ios-11-cisco-wireless/ https://alcatron.net/2017/12/13/apple-ios-11-cisco-wireless/#comments Wed, 13 Dec 2017 05:30:27 +0000 http://www.alcatron.net/?p=810 I recently have purchased 2 x Cisco 3802 , and 2 x Cisco 1852 Access points to work with the Cisco 2504 WLC Controller. I really wanted to upgrade to AC wifi and take advantage of all that Cisco have to offer in the wireless world and put it through some tests and performance. Initially i found it great on Windows Laptops and Macbooks, however i had major issues with Apple IOS 11 and Apple TV. Connections would constantly drop and would not work as well. I was testing on the 5Ghz/80Mhz band, and i seriously thought there was an issue with this band, as switching things to 2.4Ghz/20Mhz seemed to work better.

I raised a Cisco TAC case to further investigate these issues and we found that:

1) Optimized Roaming was enabled for 802.11a and 802.11b. (On WLC: Wireless > Advanced > Optimized Roaming)
This caused many issues with the Apple TV and Iphones/Ipads, and disabling this fixed the Apple TV, but not fully the Iphones and Ipads.

Optimized Roaming Settings on WLC, remove the ticks

2) Fast Transition was enabled with Adaptive (On WLC: WLANS > “Your SSID” ID > Security > Layer 2 > Fast Transition)
Having Fast Transition enabled caused the significant issues with Iphones and Ipads with wireless connectivity and dropping. Once this was switched off we immediately noticed the performance improvement and roaming.

Set FT to Disable on WLC

Cisco advised that the IOS  11 is buggy when it comes to the implementation of Fast Transition as we went through many debugs. They advised I needed a Apple Enterprise Support contract for Apple to just look at it, which I couldnt afford, so I have left Fast Transition “off”. The enterprise contract is like $5995 USD, or $799 USD per incident, just a bit pricy!

I also asked if there was any benefits to Fast Transition being “on”, and they advised it was only beneficial if my wireless setup is 802.1X and this improves the roaming between AP’s and going through Radius etc. My scenario only had WPA2 Pre-Shared key, so i could leave the Fast Transition set to Off without any issues.

Cisco Apple best practice document found here, advises FT should be set to Adaptive and left on, however as we found IOS 11 has severe issues with their implementation of FT..

I queried Cisco whats going on here.. and why there is so many issues and differentiates from their document and their advise was:

FT will always be suggested on Apple enterprise environment. This can’t be removed from the document simply because new iOS on some devices are having buggy issues with it. This is something that need to be fixed on Apple side and Cisco has nothing to change on the code or document since we are following the IEEE standard that we expect Apple to also follow on their entire product line.
Unfortunately as shared before to engage Apple care , you need to have an “enterprise AppleCare support agreement” contract.
TAC can’t do anything from Cisco side for this case to move further unfortunately.

So for all of you reading and have Cisco Wireless setup, running IOS 11, and are noticing problems with Apple TV/Iphones/Ipads be warned what options are set on the WLC, and how it could affect the wireless experience.

For Apple reading, please look at your FT implementation with Cisco on IOS11, so its less buggy, especially on the 5Ghz bands.

Again, thanks for reading and any feedback welcome.

Leaky Gut Update – Zonulin https://alcatron.net/2017/10/06/leaky-gut-update-zonulin/ https://alcatron.net/2017/10/06/leaky-gut-update-zonulin/#respond Fri, 06 Oct 2017 11:15:13 +0000 http://www.alcatron.net/?p=804 Since 2013 as you may have noticed from my previous blog posts I have been suffering from leaky gut caused by the Klebsiella bacteria. Since then i have managed to clear the Klebsiella bacteria. But even then still something isnt a 100%. Usually on a daily basis i feel 85%, but something still isnt right with the other 15%, while keeping on a tight restrictive low histamine and clean diet for 3 years now. No sugar, processed foods for 3 years! Its tough but I have part of my life back.

I recently took a food intolerence test like I did in 2013, the original one that I posted. I had IGG allergy to 49/269 foods.  This time I took at test for 93 foods, and only 2 came back , 2+ cows milk, and 1+ on almonds, and tremendous improvement over 2013 result.

So food intolorance is a step up and looking good. Also my DAO and Histamine normalized over the 2013 result which im really pleased with. I have been able to tolerate aged meats more..

BUT HOWEVER……………………. The test for ZONULIN which tests the gut wall leakyness through blood test, the result went off the charts, so I still have inflammation of some sort showing there at the gut level. The aim now will be to further analyze stool test at a more detailed level to see if any other bacteria are lurking preventing the full healing.

The latest result:

Zonulin 90.0 ng/mL (But should be in range 20.0 – 48.0) ,

Diamine Oxidase 26.0 units/mL (Yes! mine falls under Low Incidence)

Ranges:
> 10U/ml – Low incidence of Histamine Intolorence
3.0 – 10U/ml Probable Histamine Intolerence
< 3.0U/ml High incidence of Histamine Intolorence

Histamine 43.0 ug/L ( Normal Range 28.0 – 51.0) Yes! its in the within range.

The Zonulin and Histamine tests were done through Nutripath in Australia through a practitioner.

So what we have is:

  • Eliminate Klebsiella – Check
  • Eliminate/Reduce Food Intolerance – Check
  • Eliminate/Reduce Histamine Intolerence – Check
  • Bring Leaky Gut back to normal within range – something to work on still

Also i am keeping on an anti-inflammatory diet, as im still inflamed due to the high zonulin, but its a work in progress!

Long journey for the past 3-4 years I only hope it gets better, will keep you updated!

Are you wanting to know more about Zonulin, and how it really impacts your health? Take a look at this video
