Question
Internet Only - Guest Access Setup in DD-WRT
I'm going to be allowing a neighbor to use my wireless network. I want to set them up such that they can get to the Internet but cannot access any part of my LAN (printers, file servers, other routers, etc).
The main router is a WRT54G with DD-WRT v23 SP1 (I know, I need to update). I'd like to keep this all within this one router and not have to add another one if possible.
How do I do this?
Thanks!

DD-WRT is nice, but not that advanced. You need to have him on his own subnet and the only way to do that would be to have him on his own router. Then on your main router you can put in routes for his subnet that only allows him access to the internet. Say you main subnet is 192.168.1.0/24, you would put him on a subnet 192.168.0.0/24.
Then you set a default route for 192.168.0.0 out to the internet. Then set routes for 192.168.1.0 that go no where.
I must say I successfully set this up on a DD-WRT firmware and it worked however I had many problems keeping it going. after a couple days it would start dropping packets for this restricted network and the only way to get it going again was to delete the routes and put the same ones back in. Also each route i used, individually would work, but once I started getting 5 or 6 routes everything would stop working. And i would have to back some out. I don't know if this was a problem with the firmware or just a crappy router, but I ended up getting a linksys vpn router and using the standard linksys firmeware to create these rotues, very stable. never had a problem.
