We are an organization of 3 people who need to connect to our head office's VPN using Cisco VPN Client 4.0.5(Rel) client software over the Internet. We have installed the Linksys WRT54G (version 5, with Firmware Version: v1.01.0) wireless router with a Static IP address, and are using its DHCP server. We all have access to the Internet, however only one person can be logged into our VPN via the Cisco client at a time. If a 2nd or 3rd user attempts to log in, the other connected user is bumped out of the VPN and loses that connection. How can we overcome this issue?
We are using the VPN client with IPSec/UDP and have enabled Transparent Tunneling. All 3 of us do use the same Group Authentication name and password, but we each have different accounts when attempting to log into our VPN (each person has a unique Username and Password).
Any thoughts on how we can overcome this? I have tried switching to TCP, but that would now allow us to connect - so I think we need to use UDP. Would Port Forwarding work? If so, how would I set that up for both the laptops we use, the VPN clients, and the router?
Any help is much appreciated.
Thanks in advance, Morgan
