That is what I was doing, with no success. &nbsp; I changed the rules to a static NAT with the IP of the server and everything works now. &nbsp;Thanks!

I Just added a Watchguard XTM 21 firebox and I cannot connect to our Server 2008 using RDP. &nbsp;We had a Linksys router firewall before and there were no problems connecting before. &nbsp;I have already allowed the RDP rules in the firebox and I believe everything is forwarding correctly to the IP of the server. &nbsp;No matter what I try I just cannot make a connection. &nbsp;I cannot find a whole lot of information on the forwarding rules for the watchguard firebox. &nbsp;Any help would be great!

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.
