Re: OT: L2L Tunnel wont come up!!

Hi Steve,

Looking at the debug output I noticed the following:

*May 16 2011 01:35:09.394 PDT: %SEC-6-IPACCESSLOGP: list 101 denied udp
10.70.100.100(500) -> 10.70.100.55(500), 7 packets

It seems your ACL 101 is dropping the IKE traffic (UDP Port 500) which is
causing the problem. Try allowing IKE in your ACL and then putting the deny
ip any any.

HTH,

Thanks

Take Care
