Bridging two houses 0.5 miles apart

    I want to use two WRT54G's to connect two houses about 1/2 a mile apart with a clear line of site - I will use cantennas to do so (www.cantenna.com).

    The idea is that computers from House A and House B should be assigned NAT addresses and be all allowed to browse through the cablemodem connection in House A out to the internet.

    The only wrinkle is that neither house wishes to see the other house's computers in the network.

    Is there a way to block communication between the houses but still let all computers browse the internet through the same connection?

    You can assign the computers of each house to an own workgoup. But this is a windows-setting and has nothing to do with the WRT54G routers. In combination with a proper setup of user-accounts, security-policies and passwords on each computer this is pretty secure.

    As an alternative you could add an iptables rule, that blocks alls traffic going on TCP port 139 (this is the netbios port used for windows file and printer sharing) to the other router.

    Thankyou very much for your reply. I look forward to trying it out once the routers are in place.

    Another simple solution would be to install a software firewall on all the PC's in house A and configure a rule that blocks all inbound connections from the IP addresses in house B. Using a custom firmware you could insure that the PC's in house B always lease the same address. (Wouldn't prevent the PC's in house B from manually assigning a different IP address though.)

    I am currently sharing my DSL with my neighbor. If you have a line of sight with each other you can use a cantenna. I purchased one of these and I did not expect it to work. I setup the cantenna on a tripod and pointed it in the general direction to my house and I had a 50% signal without even fine tuning it. It works great. I even had it getting a 40% signal with my WRT54G in my basement. I think you can get a great signal if you use two cantenna pointed toward each other. I was lucky and only needed one.
