Are you trying to send from one device on your network as port 8123 and get it delivered to another device also on your network into port 443?
If this is the case you need to send the data out to the internet using you VM Internet address and then when it comes back into your router you need to port forward 8123 to 443, so it goes to the second device. I know no other way of doing it as port forwarding only works from Internet to Intranet.
There are 10 types of people: those who understand binary and those who don't
no the two ports i.e. 8123 to 443 are of the same device. I have read in the forums that the superhub are not smart to allow port forwarding from one port to another but jus wanted to confirm if this is true?!
