Required Firewall Ports for Nortel VPN Client

[zghortaman]

Hi, I’m looking for some advice. I use the Nortel VPN client version 4_15.06. I can connect just fine (WinXP Professional) to my org’s Contivity switch when I set my PC’s to go through my home firewall/router’s DMZ. But when the PC is set to not go through the DMZ, I can’t connect (I get a “remote host not responding” error). I’ve opened up the following ports on my home firewall/router (it's a Compaq IPaq Model CP-2W):

21 (TCP for FTP)
80 (TCP for HTTP)
144 (TCP for News)
23 (TCP for Telnet)
110 (TCP for Pop3)
25 (TCP for SMTP)
6699 (TCP)
6257 (UDP)
500 (TCP & UDP)
1723 (TCP & UDP)

I must be missing a port or two to open. Any advice would be greatly appreciated!

Thanks in advance!

I figured out my own answer. The IPaq CP-2W home router/firewall has a virtual server component. It's necessary to foward ports 500 (UDP) and 1723 (TCP) from global to local within the virtual server configuration. After I did that (thanks to some advice from the Compaq website), I was able to easily connect via VPN.
