How do I get an IOS router to do IPSEC over UDP for a lan to lan connection? I have enabled the 'crypto ipsec nat-transparency udp-encaps' but it still won't pass traffic.
I have a firewall between the IOS router and VPN Concentrator but the VPN client works 100% with IPSEC over UDP but not the router.
I get a connection and the SA on the concentrator shows send and receive but the SA on the IOS side shows encapsulation only, I have a 0 for decapsulation.
Thanks in advance!!

Check the encryption settings on the router. It should match the one on the VPN concentrator. Thats one of the major for no decryption.

Yes, they are exact. I actually get the SAs built and the other side is sending, it's just this side is not receiving.
