Lan2Lan Tunnel IKE peer Remote peer mismatch

I am buidling a second Lan-to-Lan tunnel on a 3005 concentrator. Pahse one appears to be sucessful but tunnel fails to complete with th4e following message:

Tunnel Rejected: IKE peer does not match remote peer as defined in L2L policy

IKE peer address: xx.xx.xx.xx Remote peer address: yy.yy.yy.yy

Where xx.xx.xx.xx is the IP address of the remote peer of the new tunnel. (Expected) and yy.yy.yy.yy is the ip address of pre-existing tunnel's remote peer (Unexpected, at lest by me.)

WHat I wonder is for the first tunnel I have defined the remote network as 10.0.0.0 0.255.255.255 and for the new tunnel I have defined the remote network as 10.8.111.0 0.0.0.255.

Could the overlap be a problem?

Re: Lan2Lan Tunnel IKE peer Remote peer mismatch

Make sure the interesting traffic match on the participating devices. If you have any tunnel any unused tunnel bring it down.
