How To Translate An External Incoming Port To A Different Internal Port

To set up NAT rules to translate an incoming external port to a different internal port on a SonicWALL firewall, log into the SonicWALL web interface, open the Wizard and use the Public Server Wizard. Create a port for the external port you want to translate, enter the internal IP, External IP then click Finish. Next (under Network -> NAT Rules) edit the 3 NAT Rules that the Wizard created, changing the Translated Destination to the internal port you want to forward the traffic to.
