Ang: [VPN] Win2K VPN ports

The usual stuff to allow through a firewall is
IKE (UDP 500)
ESP (Protocol 50)

If you are NATing the clients behind the firewall
there might be a problem. Some of the firewalls
have a VPN-passthrough feature, and some
don't. Some clients have support for NAT, e.g.
encapsulate the VPN-packets in UDP to survive
NAT...

Hi,
What ports need to be opened, if I set a Windows 2000 VPN behind a firewall.
Thanks,
Roger Qian
