We setup a VPN using pptp. Works OK but when we put it to the test on
the internet, the access list on our Cisco serial interface would not
permit RAS to establish the PPP connection.
I modified the list to allow any address to any tcp/udp port on the
required subnet and the test still failed. However, when I removed the
access list altogether (which by the way is a standard Cisco list) a
connection was indeed established.
Does anyone know if the router (Cisco 2514 IOS v11.1(5)) requires
additional configuration on the netbios side of things? Any thoughts
greatly appreciated - am
