Ok....i know this sounds a bit odd....but i'm running into an issue with my vpn tunnels only working one at a time. So i'm going to try and explain
this the best I can.
I have a remote router (2811) on the other side of an MPLS network. On that remote router I have set up two seperate tunnels with two seperate peers. One tunnel's peer is at the Host side serial interface of the MPLS connection and the other goes to a connection on the inside of the network on the host side.
I've tried to add a diagram to better explain.

My problem is.....I can get the tunnel to work from the remote router to the ASA to work by itself. I can get the tunnel to work from the remote router
to the Host side by itself. However, when I apply the crypto map to the serial interface on the host side to bring that tunnel up, my tunnel from the remote router to the ASA goes down. Is this because the asa being the peer from the remote router is forced to run through the HOST side serial interface which already has crypto map on it?
Any explanation would be helpful.
