Hi All

I just locked myself out. :mad: I now need to wait till I get home to open up my firewall again. :(

How do I configure this firewall thing to allow me to RDP from the office to my home machine.

I have
SourceIP: the firewall IP of my office, so this will always be the same
RouterWANIP
RouterLANIP
DestLANIP : the IP address of my pc on my LAN.

On the router, I have set up a virtual server forwarding port 3389 to DestLANIP. This works when I have no firewall rules, but I would like it a little tighter.

I assume then that I need to set up the firewall as follows:
Default Rule: drop
Rule1: Flow=in, Action forward, SourceIP=SourceIP above, SourcePort=3389, DestIP=???,DestPort=3389.

What goes in the DestIP? I put DestLANIP, which promptly cut my RDP session.

I could try each possible combination, but I have to travel home and back to work everytime I make a mistake. This could take weeks to get right....

I am really looking forward to an answer. Thanx
 
Choose any port on the WAN side, but make sure its not the default 3389, and route it to your private IP:

Example

ext 5389
internal 3389
protocol TCP
lan IP192.168.*.254
