It appears that by default this fails to work properly. I have a visitor that is attempting to connect to their Exchange server using a PPTP VPN connection, but my router is blocking it. It see the TCP connection going out but the response is unexpected and is blocked. Is this correctable through the ADSM GUI or is it strictly command line? Since our router has been working properly for several years without incident, my CLI has waned a bit. Thanks for any suggestions you may have.
