I am trying to get Cisco VPN client to connect thru a linux RH7.1 server. Server has 2 nics one to ADSL, the other to Linksys 5 port hub. VPN client software is to connect to work and is on win 98 box . What do I set on Linux server to allow VPN packets to pass thru back and forth? All other internet connections work fine thru both boxes. Only VPN is giving headaches. HELP!! I'm in a middle of a big project at work and I need the remote access to work.
open up udp 500 for ike, and udp 1000, for ipsec traffic, if it's being encapsulated, for nat traversal, if you're connecting to a VPN 3000. 1000 is the default. Your vpn admin could have configured a different port though.
you are using RH7.1. I have a few questions first: Did you set up a firewall(ipchain or iptable)? If you you need to allow the packets to flow out the port you are using as a VPN port.(L2PT or whatever ...) See also /etc/hosts.allow and /etc/hosts.deny
