RV325 , NAT 1:1 and Dyn DNS

I have a RV325 that connects multiple internal machines to the internet.  My external connection uses dyndns.  I'm trying to map each machine to a specific port range using the NAT 1:1 table combined with port forwarding.  The problem is what do I use for my external address in the NAT table?

Thank you for reaching out to us and I'm sorry you are having issues with your device.

Please let us know so that we can help.
