Redirection based only on port

Hello,

I need some advice for a setup. We have one device A connected to a router and we need it to send 443 TCP requests to a destination B in another subnet as well as 80 TCP requests to destination C in again another subnet. The problem is that on the device A we can only use one destination IP, the filtering must be done only based on ports used.

Is it possible to be done? With what kind of hardware?

I saw this post that would maybe correspond to our needs: http://ift.tt/2skPbQ9

Thanks a lot in advance!
