Hi, I have an 1801 with advanced security running on a site with a l2l ipsec vpn tunnel. Everything is working fine. I need to be able to terminate pptp vpns (Microsoft vpn client) on the router. can this be done. I would imagine I have to allow port 1723 and gre in on the main acl and also set up the pptp server on the router. Any help or config examples would be great. Attached there is a cut down config.
