  1. I have my VoIP router (regular linksys router with one less port) the 4th
    port is replaced by the VoIP connetions....anyhow, I have it hooked up
    after the Cable modem, then I have the new G router chained off the back
    of it. It's all working.....but I can't get to the config gui on the G router anymore. (once set up)
    The viop router addy = 192.168.15.1
    the G router addy = 192.168.1.1 (normal)
    I turned off DHCP Server on the G router and filled out the routing info pointing at :
    destination ip = 192.168.1.0
    subnetm = 225.225.225.0
    default gateway = 192.168.15.1

    PC's hooked to both routers get to WAN and LAN just fine as does this laptop (wireless)
    but I can no longer get to the G router to check / change settings - HELP


    I guess I dont realy need to anymore - it's all set up ..... but I should be able to, no??

    192.168.1.0 is NOT a valid IP address. You cannot have an IP ending in 0. Since your gateway is 192.168.1.1, change your IP to 192.168.1.2 0r anything through 254.

    Thanks for the reply... but the "Detination IP" is "supplied" by the router in
    it's Routing table it's a network address.

    If you look at that route you have made then all 192.168.1.x traffic is sent to the .15.1 machine. This means that when you try to access the 192.168.1.1 then all the packets are sent to 192.168.15.1

    thanks Nodsu, I changed one of the machines on the lan to use 192.168.1.1
    as it's gateway, gave it a addy in the LAN addy range and now I can get to
    the GUI on the G router - great stuff! :hotbounce

    .15.1 to .1.1

    I have the same issue, except my VOIP router is downstream from my main router... same IP's though; DSL modem > router > voip router.
    I'd like to know how add a static route to the table on my router to get to my VOIP router, for diagnostics. I tried adding 192.168.1.0 / 255.255.255.0 / dest: 192.168.15.1 as a complete shot in the dark...

    I thought an easier way would be to put the VOIP in the same subnet (if that's the right word).. I changed it's LAN ip to 192.168.1.120, but quickly changed it back when the router complained that it's WAN and LAN were in the same domain.

    First, make sure you stay in the same 'subnet' eg 192.168.1.x
    mixing 192.168.15.x can be done, but it just complicates your life.

    IP Address 0, 1, and 255 have special meanings and are not assigned to systems.
    The typical router is usually found , but not required, at x.x.x.1
    The 255 address is for broadcasting (eg Printer on/off line).
    You can assign ANY non-duplicated address as a static address.

    If I were doing this for my systems, I would assign static addresses from
    the high end down (eg: 199,198,197,...) while using the DHCP address
    of the upstream router (frequently the 192.168.0.1) for dynamic addresses.
    As long as the Mask covers the whole range(eg 255.255.255.0) and the
    gateway is also the top-most router, all systems should flow to the ISP.
