I've got a 2801 router configured for PAT. Behind the PAT, one of the clients is trying to connect to a remote Microsoft PPTP vpn connection. It connects fine, but after a period of time, dies. I want to make sure that my config isn't killing the vpn. I don't think that it is. I would appreciate a quick doublecheck. specifically I want to know if my acl in my nat statement is sufficient.
I see other posts speaking of allowing GRE and tcp port 1723, but that is for client on the outside of the PAT and server on the inside. This is sort of the opposite.
