Site-to-Site VPN Issue (newbie)

Hi,

Trying to sort out a configuration issue, but don't have boatloads of experience to sort it out.

The tunnel seems to come up, but I get "output crypto map check failed" when trying to ping a remote host.

Pretty simple site-to-site, here is a scrubbed configuration:

!
version 12.4
service timestamps debug datetime msec
service timestamps log datetime msec
no service password-encryption
!
hostname Router1
!
boot-start-marker
boot-end-marker
!
enable password Password1
!
no aaa new-model
!
resource policy
!
mmi polling-interval 60
no mmi auto-configure
no mmi pvc

Still having the issue, but I have determined that is our partner's end and we are waiting on them to make some changes so that we can test it.

I will update this thread once we get closure.

Thanks,

Hi,

I do think its the other end as well. 

Hi Aditya,

Have you had a chance to review my latest config?

Thanks,

Hi,

The interface for which you use the overload keyword should be the internet facing interface.

It should resolve your issue.

Regards,

Aditya
