I am setting up a firewall in a remote office. I need to have a VPN connection directly to this firewall for management purposes. I am doing this successfully at our main office but I cannot get it to work on the new firewall. I am using ShrewSoft for the client. It looks like everything goes through fine intitally but at the end I get an error. ShrewSoft says the tunnel is up and connected but it never shows that it is established. I have posted the error below that I see in the audit. I have tried using just a simple preshared key definition and a single certificate definition (my preference). I get the exact same error on either one I try. If anyone has some ideas I sure appreciate it.
