| We are trying to implement a PPTP VPN through a 1720 Cisco router - with only the IP Feature Set (No Firewall IOS) - to a Win 2000 server. With no access lists, it works great. With them, no dice. I have opened port 1723 for PPTP and am confused about the GRE Protocol 47 command (or whatever it is). Anyone have info on this? Thanks! | |

| Dear Kwftide
GRE protocol is generally used to create a tunnel between two gateways rather than end points. Dont get confused. | |
|
| This is not too big of a deal. GRE is a protocol keyword so you can create an access list with something like
access-list 109 permit gre src dest and apply it to the appropriate interface in the apppropriate direction.
Let us know if you have more questions.
