Port forwarding with Windows Server 2008

You need to do two things to set up what you want. You need to set up the port forwarding and then also allow the traffic through the firewall.

In ASDM, go to Configuration -> Firewall.

To allow traffic through the firewall, go to Access Rules and click Add, then enter these values:

Interface: outside
Action: Permit
Source: any
Destination: 1.1.1.1 (your external IP address)
Server: tcp/3389

To add the port forwarding rule, go to NAT Rules (below Access Rules) and click Add, then Add Static NAT Rule..., then put these in:

Original
    Interface: inside
    Source: 10.10.10.10
Translated
    Interface: outside
    Use IP Address: 1.1.1.1
Port Address Translation (PAT)
    Enable Port Address Translation (PAT)
    Protocol: TCP
    Original Port: 3389
    Translated Port: 3389

As long as you have a static IP on the server and not DHCP'd through your router...if it's a home router as some have suggested...it should work as long as you have the proper port going to your server's services.

• Verify from within the network that you can connect to the services.
• Verify that you have the correct external address (www.whatismyip.com).
• Verify that the ports are "open" and not firewalled on the server.
• Verify that the ports are "open" from the outside (nmap is your friend, otherwise you need another service to scan your external IP)
• Restart the router to verify that the new settings "took". Shouldn't need to be done, but if it's an inexpensive router, you never know.
• If you have any logging available for particular services, check the logs to see if there's any connection attempts or anything showing up on the server side.

You might want to consider with those services (FTP especially) just putting the server in a DMZ. You're really kind of opening it to all sorts of hack attempts with the services you mentioned all on one machine and I personally wouldn't want it on the same subnet as my personal machines. DMZ it and you might have an easier time than individual port forwarding.
