Multiple Routers on the same network

    we are just about to expand our current network at work and I have a question before we do it...

    Is there any way to disable NAT on the WRT54G?

    Our current network looks like this:

    Internet Connection
    Linksys BEFSR81 going to classroom computers (LAN IP:
    2nd linksys BEFSR81 going to all development computers and testbed servers (we are a web design company) (LAN IP:

    We just expanded to a second suite (right next door) and we need to add wireless access for our laptops. Is there any way we can disable NAT and DHCP on the WRT54G (which hasn't been installed yet) so we can keep all our development machines on the 192.168.2 subnet (I would like to keep with the linksys firmware, if at all possible)?

    Thanks in advance!

    Thanks! I will give that a try tomorrow.

    The only question I have in that case is would that disable NAT aswell? or just the firewall?

    Thanks for your help!

    sorry misinterpreted...

    If you had ALchemy you could goto:

    Setup->Advanced Routing, Enable Routing (eg. OSPF) but don't enable any Interface (Interface=Disabled). This should disable NAT.

    but not too sure on standard firmware.

    Thanks for your help Toxic

    If it can't be done in the standard firmware, it looks like I will just have to put it on the instead of

    That leads to my next question... If the wireless laptops are behind the wireless router's NAT, will they be able to access the computers on the 192.168.2 subnet? (The thing which I am concerned about is the laptops being able to access the testbed servers)

    If you have two different subnets the computers will not be able to see each other.

    Hmm... if the computers cant see them on different subnets, that idea goes out the window...

    Thanks for letting me know before I tried it :)

    Any ideas as to how to disable NAT then?
