Curious if I can do this with Tomato (any of the other firmwares here) I have a WRT54GS V1, currently running the latest version of Tomato. I have the following devices connected to the 4 wired LAN ports: computer 1 computer 2 computer 3 netprinter Basically, I want to set things up so that all the computers can access the network printer, but CAN NOT ACCESS EACH OTHER. My girlfriend is going to put her computer on the network & she's prone to getting viruses, so I want to sandbox her off away from everything else. Is this possible? Could someone walk me through this?
