Ok, here's the current setup. I have a Linux 7.2 Gateway that uses Ip
Masq for my internal LAN via ipchains, no ports are currently being
blocked. I need to use the Nortel 2600 Contivity Client software on
my computers within my LAN to connect to another company's VPN switch.
The Nortel 2600 needs the following open, UDP/IP 500, AH Protocol 50
and Protocol 51. I am not familiar with IPSEC so I need to know how
to setup IPSEC on my linux gateway so that my internal LAN can connect
to the other company's VPN.
Thanks,
Robert
