I'm trying to achieve exactly the same solution as the answer in this post (which works locally):
Except I need to forward to an IP address on another machine.
What do I need to do to get it to forward to an IP on another machine?
Eg: Machine A has 192.168.0.6 Machine B has 10.0.0.2
On the gateway if a client accesses 192.168.0.6 port 443 I want to forward it to the other PC at 10.0.0.2
How can I achieve this?
