subnet mask?

    My Linksys WRT54G Version 2.0 assignes ip address like 192.168.1.*
    I have a device attached to the ethernet port and it runs a web server
    on address
    I can not access this device's web server. I believe it is because my subnet mask is
    I think that if I change my subnet mask to, that I should be able to access this device.

    So if I do need to change the subnet mask where and how do I do that?
    I'm not sure if I need to set this (if I even can) on the Linksys or on my computer that is also connected to the linksys (by wireless) or both.

    My Linksys firmware version is v4.30.5

    You are correct in your thinking, if the webserver is on your internal network do one of 2 things. Change the webserver IP to the same range at the dhcp server on the linksys. Or like you propose change the linksys addressing. I am not sure of the exact place for that particular router, but it will most likely be on the very first page that comes up when you first logon to the router. If you reconfigure your router to give out the 14.0 network you wont need to do anything to your server and just make sure you have the proper ports forwarded to the server for outside access.

    Changing the Router to 192.168.14.X subnet and letting the dhcp from the router do its job will be the least ammount of work for ya.

    Well I think I should set the subnet mask to but HOW?

    Change the address of the webserver 10 something in or change the lan ip of the wrt to

    I can not modify the address of the devices web server.
    Are you saying the rest of my network needs to be changed so that I can just access the web server?
    What about the rest of my network that is at 192.168.1.* ?
    Why can't I simply change my subnet mask to
    Do I have to disable DCHP and assign ip addresses manualy to get to the subnet mask?

    How many other devices on your network? If thoses are simple client PC using DHCP to get their addresses, it would be easier to change your router's LAN address and let them renew with the newer subnet.

    I'm not sur if you can change the LAN's subnet mask in the stock firmware of the WRT54G. Going manual would solve your problem but create a new one... Since your router would be on a /24 subnet, your PCs would see your web server but your router would only see a part of the network depending of its LAN address.

    You may be able to use a third party firmware to do that if it's not possible with the stock firmware but that another ballgame alltoguether.
