Unable to establish l2l because of mismatched attr.

jsehlhorst · ‎09-03-2008

We are trying to connect a l2l between a 515e and VPN concentrator using 3DES-SHA. We are getting the following error information from the concentrator:

IKEDBG/79 RPT=1603304 Proposal #1, Transform #1, Type ESP, Id Triple-DES Parsing received transform: Phase 2 failure: Mismatched attr types for class Encapsulation: Rcv'd: UDP-Encapsulated-Tunnel Cfg'd: Tunnel

I am not sure how to change the UDP-Encapsulated to just Tunnel.

hello,

It's defiantly ISAKMP problem. Check you NAT-T on PIX - no crypto isakmp nat-traversal

Thanks.

It worked! but can you please explain how it fixed the issue and if that change will impact anything else?

Thanks,
