Port forward only from specific source IP?

What is the best way to port forward:
one specific port
incoming to fusionhub
only from specific source IP 123.456.789.123
across speedfusion tunnel to specific balance LAN IP 10.1.2.3?

Do you want to forward the same port from other sources to a different device? Or do you just want to block that port from any other source?

If you simply want to block the port from other sources you can write a firewall rule to permit inbound from the desired source, followed by another rule to block the same port from ANY.

Thanks. Forwarding one port to one destination and adding a firewall rule to block all other sources will work for now.

Are all port forwarding settings made on the fusionhub side of the speedfusion tunnel? Does the balance need a setting entered as well?
