How to allow Guest Network access to internal server with port forwarding?

[coolxal]

Guest Network prevents access to internal network. That's perfect.

However I have a server machine that is accessible externally. I have set up port forwarding to allow this. I can access the LAN IP within my network and the External IP:<port> through LTE on my phone or at work. That's perfect.

Guest Network cannot access server through LAN IP. That's what I want.
Guest Network cannot access server through External IP:<port>. This is my issue.

Is External IP:<port> being resolved to LAN IP so Guest Network blocks it? Is there anyway I can allow access to the server on Guest Network?
