Hi,

I have a laptop that has to connect to a VPN(IPSEC) server on the internet, i have a Windows 2003 Server performing NAT inbetween the laptop and the internet. The VPN connection appear to establish correctly but i am unable to contact any host on the remote network, i have forwarded the following ports for NAT-T & IPSec but still no joy. Any help would be much appreciated.

Ports Forwarded: 500(tcp/udp)
4500(tcp/udp)
1701(tcp/udp)

Many Thanks,

have you looked at the firewall logs? might help to look there to see if the firewall is blocking anything out, otherwise the issue is going to be with the established connection to the remote location (ie permissions)

You should only need to forward those ports if they're inbound connections.

What type of firewall is it? Maybe you need to allow them as outgoings - you do in ISA server. Oh, you do have a firewall, don't you? Or are you using ICS or routing on the W2k3 box?
