Re: IPSEC Tunnel - LAN TO LAN - 3DES - SHA1 - 3K CONCENTRATOR to
Based upon the logs from your Concentrator:
Mismatch: Configured LAN-to-LAN proposal differs from negotiated proposal.
Verify local and remote LAN-to-LAN connection lists.
Please check the contents of your Local and Remote Network lists and make sure the network list on the Linksys side is an exact mirror image.
If you have a local network of 10.1.1.0 255.255.255.0 and a remote network of 192.168.1.0 255.255.255.0 on the VPN3000. Then the configuration on the linksys should have a local network of 192.168.1.0 255.255.255.0 and a remote network of 10.1.1.0 255.255.255.0.
