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!!
