Wifi/client-bridge/subnets???

Ive got the basics on home networking down pretty well but when it comes to subnets, I get lost. Here's the scenario... WWW--> router 1-->gateway 192.168.1.1/255.255.255.0, wireless G AP, set to auto dhcp, max 50 clients, and has 2-3 hosts (2 cat5, 1 wifi) set to auto config dhcp. Lets call this side A router 2> dd-wrt/linksys wireless router, set to 192.168.1.2/255.255.255.0, client bridge to side A, rip2 router, has 4 (cat5) hosts set to manual config 192.168.1.(120-150), dynamic routing set to both (LAN&WAN), both router and cliets set to gateway 192.168.1.1. . And this ill refer to as side B All clients and routers can communicate and have full access to WWW. No wi-fi security at this point but will configure it later. Side A has agreed to share their WWW connection with side B however would prefer to have the bandwidth equally shared and most importantly have side A & B hosts invisible to each other. From what ive gathered so far, (Correct me if im wrong) I think im supposed to set side A to 192.168.1.1/255.255.255.128 and let it continue to autoconfig (max 126 clients) its clients addresses to 192.168.1.(2 -126). So my question is what do I set side B router and clients ip/subnet/gateway to? Any help is greatly appreciated. This share is only to remain under the conditions requested so if I cant figure this out, side A will secure its wi-fi broadcast, causing side B to cry and rust its internal parts. Perhaps even starting an electrical fire that would engulf the residence and spread uncontrollably, leveling everything in its path. A sad sight indeed. Please Help!!!

Unless you have a firewall or can put access control lists (ACL) on the router, then what you are looking at doing is not easily done since both network share a common network routing device. You would need something like a <a href=”http://www.smoothwall.org/”>Smoothwall</a> (open source) or <a href=”http://www.vyatta.com/”>Vyatta</a> (open source) or Netscreen or Cisco PIX to firewall the segments from each other.

to continue the subnet structure from A to B, set B as follows
192.168.1.128/25 (255.255.255.128), add a static route from outside interface of router b to inside router a; point the clients to 192.168.1.128 for gateway. This will not provide load balancing for you, but should isolate the clients to their own side.

——————- No

To answer your question ” So my question is what do I set side B router and clients ip/subnet/gateway to?” – the direct answer would be to set you gateway to 192.168.1.129 and make the hosts range from x.130-254

——————– No

The router on side B should be configured as a gateway which will connect to its wan using DHCP to obtain its external address. It should have an internal IP of 192.168.2.1, and an IP range of 192.168.2.2 to 192.168.2.(2 + the number of connections you expect to have) on its own DHCP server. The subnet mask can be the same.

This should allow the two networks to be separated (invisible to each other, but still able to communicate), but still be able to communicate with the internet.

Additionally, you can set the Workgroups of the machines on each side to a different workgroup name for more security between the two sides.

This works on my network. My setup is shown below.
DIR-601(192.168.0.1 – connected to the internet)<—Wireless—>DIR-601(192.168.1.1)<—Ethernet—>Computer(192.168.1.2 – Able to access the internet, but can not see the network beyond the router it is connected to.)
