First, let me show this diagram.
So we have two ISPs. PC #1 is currently connected to one ISP, and #2,#3, and #4 are all connected to the other ISP via an 8-port hub.
My question is...how do I make PC #1 be a part of the network that PC's #2,#3, and #4 all belong to? I simply want to be able to access files in the 3 other PC's from PC #1.
If possible, the solution should not include adding a router or setting up an VPN, etc etc.
Any help is much appreciated, thanks!
