WRG614 V6 and Cisco VPN Client
I had a hard time getting my home computer to connect to the VPN at work using my NetGear WRG614 V6. After messing with it for a while I had my "disable SPI firewall" CHECKED, and once I unchecked it (so that the firewall was on) it actually started working. I know it sounds the exact opposite should happen (but believe me I checked it about 5 times).
Hope this will help someone else out who is having this problem.
