Ok guys i'm usually good with networking but i have a problem thats stumping me.
At my place of employment we have 1 router setup, it passes through a linux - mandrake box that has a proxy server, 2 nic cards, from there it goes to our other switches etc. the router ip is 192.168.2.1, the linux box switches the ips to 192.168.1.*. The linux box works as a proxy/dhcp server. The linux box supplys no gateway. I plugged directly into the router and I can get internet access via the router however cannot see the network behind the linux box. I tried adding a second ip address of 192.168.1.245 with the correct subnet, however no gateway because the linux dhcp server supplies no gateway. (I also tried with a gateway of 192.168.1.4 (linux box ip) but still had no luck seeing the other network. I have no clue what to do!! I'm trying to avoid 2 nic cards in order to make this work. Does anyone have any suggestions?

Thanks!

What IP address are you using while directly connecting to the router?
What is the physical connectivity here?

  router 192.168.2.2
         | 192.168.2.x
       Switch
  |         |         | 192.168.2.?
Users  Linux   You

If both networks are physically connected on the same switch, then you should be able to just add a secondary IP on your one NIC...

router 192.168.2.1 goes to linux server, proxy-mail server, my computer, another pc
linux server 192.168.1.4 goes to switches, rest of entire network
proxy-mail server 192.168.1.2 goes to switches, rest of network

my ip is 192.168.2.*
i can see no one except other pc
i wish to see everyone, including those with the 192.168.1.*
i added second ip of 192.168.1.* but had no success

hope that helps

Are you trying to connect to computers between the router and the  outside port on the linux box from a computer connected to the inside port?
Is it posible to give the computers in the dmz real address instead of nat? The reason you cant see them is probaly due to the proxy server blocking the connection to the nat addresses.

Just to make sure I have the topology straight:

WAN--> Router---->Linux----->switch-----> users 192.168.1.x
                       ---->You
                       ---->PC2
                       ---->Proxy/mail

If this is the case, you'll have no choice except to put in a 2nd NIC and plug that into the switch with a 192.168.1.x ip address.

WAN--> Router---->Linux----->switch-----> users 192.168.1.x
                       ---->You ------->|
                       ---->PC2
                       ---->Proxy/mail

yea trying to connect to computers that are connected outside the router, but rather through the linux box to the router,
what kind of real addresses you mean? like actual ips? i'm somewhat confused, they aren't really in a dmz i'm just keeping them away from the linux proxy because it blocks everything as far as downloads go
