Maybe with some more information you guys can give me some help and understand better
To keep things simple: I have a PC (PC 1 Windows) with the IP of 192.168.100.123 connected to a router (running Linux) which has two ports. Port 1 has a IP of 192.168.100.1 so they can see each other because they are on the same range. Now Port 2 has a ip of 10.10.10.1 and it is connected to another PC (PC 2 Windows) with a ip of 10.10.10.123
If I SSH into the router, the router can see (ping) both PCs. Its just the PCs cannot see each other.
What I want to do is from PC 1 access/send/transfer/etc information to PC 2. The router is very limited. Changing IPs is impossible
in this case. There are no other devices, just these 3.
