I want the following setup:
Internet ---- Cable modem | | +--- Router A ---- PC . . (wifi) . . . . [PC, tablet, etc.] . . HTPC Linux Mint 15 | +---- TV | | +--- Router B ----+---- PS3 | +---- Receiver
I currently have internet access at HTPC through wifi from Router A.
I want to have internet access for HTPC and devices after Router B.
As of now I don't care that devices after Router B see devices before Router B.
I would like to know how to get internet access for devices after Router B, while keeping internet access of HTPC. HTPC might occasionally pull internet content through OpenVPN.
I tried [Networks Settings] => [Wired] => [Options] => [IPv4 Settings] => [Method:] = "Shared to other computers" on HTPC Linux Mint 15, but it didn't work. I don't know anymore where to look to find a solution, if any.
