There are two forms of a CBOS port forwarding rule.
Open port 2222 on the WAN side and forwards it to the internal address.
# set nat entry add 10.0.0.6 2222 tcp
Open port 2222 on interface 23.34.45.22 (this IP is made up-the rule we used had their real outside IP address) and forwards it to 10.0.0.6. This rule worked (note: if the node has a dynamic IP these rules will break when the IP address changes)
# set nat entry add 10.0.0.6 2222 23.34.45.22 2222 tcp
