Accessing two networks

[zmunawar]

Hi all.

I have a ADSL modem connecting to internet on IP 192.168.31.x. I have a proxy server with two LAN Cards.Card A on network 192.168.3.x and network card B with IP 192.168.31.x. Ethenet card B is attached to ADSL and A is attached to LAN via cisco 2950.So, my LAN is on 192.168.3.x.I also have wireless and DHP enabled on ADSL.Users with wirelss cards get there IP's from ADSL of 192.168.31.x network and have access to internet.While ethernt users have 192.168.3.x network.

Now, my printers are also on 192.168.3.x network. I want to ask two things..

1- How can my wireless users can access printers and shared resources on network 192.168.3.x as they will be getting 192.168.31.x network.All the wireless users have XP in there systems.

2- I want to restrict my Wireless users from using my LAN proxy server.They should be connecting to ADSL via wireless.My ADSL doesnt support dual networks.it is of U S Robotics.

As prosy servers, i have both ISA and SQUID (LINUX)

Thanks all....

From the configuration you have, that would expose your internal network to Internet traffic. I don't recommend it.

You might want to set up a DMZ for the wireless with a few static NAT mappings through your proxy server to some printers. It's kind of risky though. No traffic should go from the DMZ to the LAN unless it's requested from the LAN.

What's causing you to not want the Wireless computers on your LAN?
