Topic: Which ports for PPTP?

[Hans Pedersen]

I want to be able to remote our E-Smith server with a PPTP VPN tunnel. But between the server and "the Internet" is a router.

Which ports must be forwarded to the E-Smith box (TCP and UDP)?

TCP Port 1723 and GRE Protocol (47).

If your router can only forward TCP and UDP protocols, but not GRE, you won't be able to use PPTP VPN.

This works for me (in Denmark) with a standard Cisco 677:

ccos>enable
ccos>set nat entry add 192.168.1.100 1723 207.46.230.219 1723 tcp
ccos>set nat entry add 192.168.1.100 1723 207.46.230.219 1723 udp
ccos>set nat entry add 192.168.1.100 1723 207.46.230.219 1723 47
ccos>set nat entry add 192.168.1.100 0 207.46.230.219 0 47
ccos>write
ccos>reboot

First IP number is your SME server (inside NAT)
Second IP number is your real public IP number

Unfortunately the router we're using (SMC Barricade) doesn't support GRE or 47 port forwarding... I guess I must give up accessing our SME Server Manager from the outside. 8-(
