Since installed Tomato, I can not access anything on LAN

    Before I installed Tomato, I was able to access my Motorola Cable Modem by simply typing its IP address and I was on its webpage.
    I was also able to log in other devices (VOIP devices) by using the address assigned to them by my routers DHCP.
    Since my router running Tomato......I am not able to reach anything on the connected LAN ?
    Any suggestion ?

    Are your devices all able to reach the Internet? Are your PC and the other devices on the same subnet? Which Tomato version? (Toastman's Tomato has DHCP disabled by default.)

    Are your devices all able to reach the Internet? YES
    Are your PC and the other devices on the same subnet? YES 192.168.2.xx
    Which Tomato version? Shibby K26RT-N v117
    (Toastman's Tomato has DHCP disabled by default.).....bad idea, caused headache to too many people !

    Have you put the modem address in the "route modem ip" field as it is on a different subnet than the router?
    It's on the basic -> network page.

    That's what has to be done with my modem in bridged mode.

    Same subnet? ROUTER gives them ip address on the same subnet (192.168.2.xx), but devices has their own static ip address too....cable modem and voip devices has
    However, I was able to reach them thru their assigned dhcp address, like 192.168.2.xx...i looked address up in the connected devices section

    No, I have not done that, i am going to try.

    My router is set as a "gateway", not as a "router", does it matter ?

    Route modem ip : worked, now I can see cable modem webpages
    But what can I do with other devices connected to LAN?
    Maybe change all their static LAN address to an unused 192.168.2.xx. ? (outside of dhcp range)

    Have you power-cycled your cable modem (not reboot, but an actual power-cycle)? These things pretty much indefinitely cache ARP and cause all sorts of problems if you change out the router connect to the cable modem's LAN port.

    I use TomatoUSB (specifically tomato-K26USB-NVRAM64K-1.28.0505MIPSR2Toastman-RT-N-Ext.trx) on my RT-N66U (and have done the same on my RT-N16, though not the NVRAM64K firmware obviously) and have never had to make any kind of "one-off" adjustments in Tomato ANYWHERE to be able to access from any machine on my LAN (and my LAN is, but yours is, but it doesn't matter really).

    P.S. -- I strongly disagree that DHCP-disabled-by-default in Toastman is "causing headaches". If you already have a DHCP server on your network and suddenly you introduce a router which does DHCP, take a guess at what happens? (Answer: total chaos) So it's good it's disabled by default. Besides, to turn it on all you have to do s statically assign an IP to a system, access the router, and enable DHCP once. Cry me a river if this is too much work :p

    to koitsu
    --I am using Shibby's v117, which is different from Toastman's, more heavily modified from original tomatousb
    --I am trying to access LAN devices through WIFI, maybe only WIFI access is blocked, going to try though the wired connection

    --dhcp enabled introduces chaos?
    I bought a K26-USB-RT-N router, because I needed something better (newer, faster CPU, more memory,USB,more features, etc...) than I already have.
    Therefore it will be placed instead of the previous old router.......right after the Cable/DSL modem so all the traffic will go through it.
    In my case (and in case of most of the other people) it makes no sense to connect it to the end of the system, (after another router).

    1. advanced->wireless-> make sure ap isolation is NOT checked
    2. sounds like subnet mask was not before, but is now.

    no, both were as you said:
    AP isolation was DISABLED
    LAN subnet was
