Firebox x750e changing port forwarding
Posted on 2009-07-14
I am changing the a port forwarding rule and create a second new port forwarding rule on a Firebox X750e at one of our offices. I am not familiar with watchguards. I simply want to make a rule to forward 5900 to internal address 192.168.1.247.
We have a single external public IP address connected to the WAN port of the firebox. There are several standard port forwarding rules pointing to 2 servers already. I attempted to model my new rule off of these and cahnge the existing RDP rule.
I have made the change a dozen times and cannot figure out why it does not work. for a test I took an existing rule forwarding RDP 3389 to 192.168.1.225 that is working and changed the NAT setting to 192.168.1.247. Same rule, same settings and it doesn't work! Change it back and it works with the original .225 server. Internally that system is up and accessible on both protocols.
I am guessing that there is another place that a NAT setting or the .247 host must be defined, but I can't find it or find it mentioned in any directions.
