adding pptp / vpn access to a 1720 router

[jwynn]

Can someone assist me in the command that I would use to add pptp to the router allow folks to vpn to our windows 2000 server. I also have NAT on the box..I believe it should look something like

ip nat inside source static tcp x.x.x.x x x.x.x.x x extendable. - what port should I use??

thanks

It sounds like you are running IOS Firewall feature set and you need to open ports for PPTP. I know you need 1723 tcp and IP Protocol 47 but I’m not sure if PPTP works with NAT. You might check with Microsoft on that one.

thanks. I'll try using 1723 tcp and see what comes of it.
