This weekend I found a fix to my VPN problem. I have tried this and it worked no problem

To Use the latest patch to Apple AirPort Extreme and the Nortel VPN client do the following with the latest version of the Nortel VPN client (v6.01).

1.) Update your airport utility to 7.3.1
2.) Reserve a IP address based on your computers MAC address so that your TC dhcp gives you always the same IP address. You can do that with airport utility/Internet/DHCP/DHCP-Reservations
3.) Create a port forwarding under airport utility/advanced/port forwarding.
a.) Create a customized port forwarding for public UDP port 500 to private UDP port 500 for the private IP address you assigned in step 2.) to your computer
b.) Create a customized port forwarding for public UDP port 10001 to private UDP port 10001 for the private IP address you assigned in step 2.) to your computer
c.) Create a customized port forwarding for public TCP port 50 to private TCP port 50 for the private IP address you assigned in step 2.) to your computer
d.) Create a customized port forwarding for public TCP port 51 to private TCP port 51 for the private IP address you assigned in step 2.) to your computer
4.) Update your TC
5.) Disable “Keepalives” in your Nortel Contivity tool under “options”
6.) Do not check “silent keepalives” in your Contivity client under “options”
7.) Try to establish a connection and wait until Contivity tried all availible connections.

Let me know if this works

Here is a screen shot of the port setup

Just a quick blog to warn people of a problem that I had last week with my AirPort Extreme Base Station and my company VPN.

1st off let me say when I spoke to Apple Support they told me that Apple to not support any VPN on there router’s, NOT what they told me when I bought the AirPort Extreme Base Station so that didn’t put me in a good mood.

Last week I was unable to connect to my company VPN (Nortel Client) after a number of different test I worked out that it was my AirPort Extreme Base Station that was the problem. After speaking to Apple I found out that earlier in the Week Apple had updated my Router and that is want caused the problem with my VPN.

To fix the problem i had to revert to the previous version of the software (The version that caused the problem was 7.3.1 and I had to revert to 7.2.1)

To fix the problem using my Mac I had do follow

1. Open Airport Utility
2. Click on Manual Setup
3. Click on Base Station (On the Menu)
4. Click Upload Firmware
5. From the drop down choose 7.2.1
6. Click OK

After the restart all should be good, at least mine is now working.
