    I'm still a newbie at this networking stuff so please bear with me. I'm trying to help set up a home network based on Tomato.

    Here's the setup:
    A wireless router (WRT1) running Tomato is hosting the Internet with wired connection to a PC (PC1) and wireless connection to PC2.
    Another Tomato router (WRT2) is wired to PC3.
    WRT1 (, DHCP on) and WRT2 (, DHCP off, configured as an AP) are wired through their LAN ports.

    If the physical setup cannot be changed, how do I configure it so that:
    1. PC1-PC3 can all be set with static IP addresses (WRT1 DHCP off), making WRT2 the sole DHCP server for guests' wireless notebooks? The Internet is often shared among friends who bring their notebooks with them. I've tried disabling DHCP on WRT1 and enabling WRT2 DHCP, but that didn't work with a wireless notebook I tested with.
    2. Guest notebooks cannot access WRT1, only PC1-3 have access to it? With the current AP setup, wireless guests cannot access WRT2's Tomato GUI, but can access WRT1's, probably due to it being wired to WRT2.
    3. Guests cannot access the LAN, only PC1-3 have access to it? Would a separate LAN be required? If so, how should I go about doing that?

    I don't know if any of the wireless options in Tomato v1.11 (AP+WDS, Wireless Client, Wireless Ethernet Bridge, WDS) other than AP will work in this case, but I have a feeling that I'd need one based on the reading I've done through the forum(s). I'm just confused as to which I need.
    TIA for any input.

    The problems sounds like a routing issue so I have documented a set-up I have done in the past that may help you..... I am not sure why you have 2 routers however and are effectively using one as a switch/AP only as this may be adding complexity for you here but it does give you an option here to get this working.
    Connect to cable from WRT1 in to WRT2's WAN port and configure the WAN port as a 192.168.11.x address the change that actual router address and Dhcp Ip range on the WRT2 to another subnet e.g. 192.168.12.x turn "rip" on within both routers so they will automatically "see" each others routing tables etc. This effectively gives you 2 networks and as the routers are on different subnets the dhcp servers in both can be turned on WRT1 will give 192.168.11.x addresses and WRT2 will give 192.168.12.x addresses.

    However this does add one complexity if you run mail or web servers you need port forwarding if these services are on pc's connected WRT1 fine they will work as they did before and are only needed on WRT1, however if they are on WRT2 you need to forward the port on WRT1 to the WAN ip address of WRT2, then forward it again in WRT2's config to the PC's 192.168.12.x Ip address....

    Hope this helps...
