I have several external devices that I want to add to my home network

For example: no real devices or IP addresses

Canada central FQDN device 1 20.201.84.235
Japan west FQDN device 2 135.91.19.122

The port forwarding rules I need are:

Outgoing TCP 443

Incoming UDP 3239

However, once I successfully add the first line, I get the message (Port Conflict) when I try to add the second line. How can I add multiple rules for many external devices with the same ports using the Experia 12 modem? I hope this makes sense.
