Sharing internet with neighbor, how to wall off?

[eli2k]

I'm going to split costs with a neighbor and share my wireless connection. My question is how do I go about walling off my own network, ie how to keep the neighbor from browsing my own network. Would setting up a second router (which I have available), connect it to the primary router, work? They would have their own SSID and password. In the event that the neighbor incurs a virus that is able to spread through a network, is there any way to prevent it from jumping onto my own network?

Thanks.

You could have two separate subnets/broadcast domains.

The trick is to find a router that can support a main SSID and guest SSID, and find a network with the requisite firmware.

I know my router has wireless isolation which can be set on each band. Maybe you can give them one wireless band and you take the other?

Assuming that it is allowed by your ISP (most ISP do not allow such sharing).

Cisco E4200 allows for a "guest" SSID that is on a different subnet.

This router is dual-band and also supports Guest SSID, and it's not all that expensive. I have one and flashed it to DD-WRT, then Tomato, and I am pleased with it so far.

Correct me if I'm wrong, but between the 2.4 Ghz (main), 2.4Ghz (guest), and 5 GHz bands, wouldn't there potentially be 3 different SSID's?

same DNS though so probably not best from a neighbor being sketchy.

You can install reasonable measures that will protect you from your neighbor, but I hope your neighbor realizes that the security measures do very little to protect him against you.
