I have a cisco 2621 running IOS ver 12.1 with the firewall feature set and I'm having trouble connecting to a VPN endpoint outside the firewall. I have UPD port 500 along with ESP, and AHP opened for both inbound and outbound traffic. The only thing I've been able to find on the internet says I should use NAT-T, but its doesn't appear to be support until IOS ver 12.2(13). Does anyone know a a way to make this work without upgrading the IOS? If not, will an IOS upgrade solve the porblem?
