I posted on this matter a while ago but I am unable to update the existing thread (see below)
At the time I posted that the only way I can use Nortel VPN client is to disable some of the firewal features:
Smart Firewall->Advanced Settings and disabling the following:
Block all Network traffic = unblocked
Stealth Blocked Ports = Off
Stateful Protocol Filter = Off
One of the friendly chaps on here yogesh mohan suggested opening some ports etc (as detailed in the original thread). I finally got round to trying his suggestions but it still does not work unless I turn the above Stealth and Statefull stuff off.
I did the ports that yogesh suggested (both local and remote ) and I also tried port 500 - but it made no difference.
Can yogesh or anyone suggest anything else - or am I safe to continue working with the above Stealth and Stateful stuff turned off??
Thanks!
