Provide access to LAN through firewall 1

[vickero007]

Here is my situation:

I have an XP Pro machine I've given a public IP to. Currently it sits behind a firewall in the LAN that has a different subnet mask than the XP Pro machine. I want to enable Remote Desktop to allow a user to connect to the XP machine through Remote Desktop Client while the firewall allows that user to pass through.

So the XP Pro (Subnet 255.255.255.249) need access to the LAN (Subnet 255.255.255.1) and the remote user needs access to the XP Pro through Remote Desktop.

How should the TCP/IP settings be configured on the XP Pro? I've tried everything including putting a lot of rules in the firewall allowing access. Do I have to allow connection to the XP Pro outside the firewall? Even then, how do I allow it to connect to the LAN since it is a different subnet?

The XP Pro box should be on the same network range as the LAN, not on a live IP address. It can then talk to the local network as normal.

On the firewall you can ceate either a static NAT rule or a port forward rule to forward RDP to the internal machine.
