there is package used for forward coming requests from Internet to a specific IP:port to an internal IP:port?
I try to explin better.
My cubox is in my demilitarized zone.
I would use it for forward requests to my internal nome network (and reverse back TCP response).
I.e. Supposing in my network home runs a service on 192.168.1.65 port 5625 I would to have a software that when come request on my external address (18.104.22.168 , port 5677) he forward it to my internal host /port (192.168.1.65 port 5625) follow a hand configured routing table allowing to access to service from external.
I know this is a typical router software but my router don’t allow this.
