RE: Microsoft VPN through a router [7:72824]
For IPSec I believe you need protocolsport 500. The 50 is a protocol number, like UDP is 17 and TCP is what? 6? It is not a TCP or UDP port number...

Re: Microsoft VPN through a router [7:72824]
Steve, You need to open GRE to from any source to your VPN server and then depending on whether you're using PPTP or L2TP make sure you have either tcp/1723 or tcp/1701 open. My ACL looks like this for PPTP access... access-list 101 permit tcp any host eq 1723 access-list 101 permit gre any host Stevo Steven Aiello wrote in message news:[EMAIL PROTECTED] I was wondering what ports I would need to have open for a Microsoft VPN connection on my router.
