I work for a little company. We are trying to configure a legacy Watchguard Firewall but we can't guess on how creating rules for external access to an internal server through an specified port. I did this in my router at home, to redirect to my webserver, and it worked like a charm, but I see it is not the same with this Firewall device.
Can someone help us on this?
We have an external (public) IP address (suppose IP 188.8.131.52)
We have a Watchguard XTM 515 Firewall
The internal server has IP 192.168.1.100 and uses an specific port (suppose port 57690)
We want all external (internet) incoming connections to our external IP 184.108.40.206 port 57690 be allowed and re-directed to our internal IP 192.168.1.100 port 57690.
