I have installed a WRT55AG firmware version 1.1 wireless router connected to my cable ISP. I'm able to get internet access fine. Where I'm running into problems is when I try to use the Cisco VPN Client 3.6.1 to connect to my office. I only run into this problem when I use this router. If I use my Netgear (MR314) router Cisco VPN Client works fine. Do you have any suggestions on how to fix this problem using Cisco VPN through the WRT55AG router?
