The problem I am having is very strange and I have tried to upgrade the IOS on the 1841 to solve the problem but no luck. The issue is when I enable Zone Based firewall security on of the 1841 routers two VPN site-to-site tunnels stops working. If I turn off CEF (no ip cef) then the traffic for both tunnels works. Someone told me that the Zone Based firewall must have a match for the VPN traffic and I created that with ACL 160 and 161 but it did not solve the problem.
Looking for some ideas on what else to try?
Current IOS is below.
