WAN info retrieval possible?

    Can the WRT54GS router be set up in such a way that it can be connected to a different ADSL modem and not require any setup info be entered manually? Currently it is in the Gateway mode, and I haven't figured out what the Router mode does or if that is what I need. I tried changing to the router mode and it kills my access so I don't know how it is used.

    The preferred way to use a router with ADSL modem is for the modem to be in bridge mode with the pppoe login details in the router. You may be able to put your modem into half-bridge mode and then use auto-dhcp in the WAN config for the router which is how a factory default config on routers can work 'out of the box' with some cable services.

    Only if your ADSL modem can be set to routing mode instead of briding mode. The gateway/router mode in the router is for something else.

    The ADSL modem is set for connection type PPPoE, but I haven't found where it says bridge or half bridge mode yet. There are about 40 tabs on the setup menu and some pages have additional screens you can display, so I've been getting more and more confused trying to learn what all the different settings do.
    Right now I'm trying to learn enough to understand what is going on before I start making any changes so that I can undo things if it quits working.
    I'm making notes trying to get all the info in some sort of order and appreciate all the help I can get. I've been googling, reading, and asking questions for days now.

    If the ADSL modem is set for PPPoE in itself, then it's performing the routing, and if your other modem is also set to connect by itself, then you can connect your WRT54GS router to either of them without any changes.

    That's what I would like to happen, but I may have set up my WRT54GS improperly as it contains the WAN settings of the Satellite terminal right now and I'm not aware of how to use it without entering those settings. The Satellite terminal connects just by powering it up, with or without using the router. The ADSL modem also connects without need of anything other than applying power. Both devices contain their own login and password info. I believe I need to make changes in the WRT54 so that it does not contain any WAN information, unless it is something which would be common to both the Satellite terminal and the ADSL modem. Only one of them will ever be connected to the WRT54 at any one time.

    If both your satellite and ADSL connections can connect by themselves, they should be doing routing/NAT by themselves already. Shouldn't you be able to connect a simple switch and be able to share the connection?

    I'm working from a point of possessing very little knowledge and it appears that reading volumes of material has not improved my understanding of what I am working with.
    I am assuming that since both the ADSL modem and the Satellite terminal contain all the necessary info within them to build a connection, the output side should not need to be aware of any specific information related to the computer connected, or should perform simply like a dialout modem.

    I then assumed that by adding a router, it would appear as a single computer connected to either the ADSL modem or the Satellite terminal, whichever was connected to it at the time, while the router would see nothing more than a connection to the internet.

    The router, I assumed would then be the single piece of equipment which would have information related to the individual computers connected to it, and allow me to specify specific ports where desired to be used by individual computers.

    I preferred to set my own IP addresses for each computer, and have all equipment belonging personally to me contain no changing IP addresses. The WAN connection of the Satellite is a fixed IP, but the ADSL is dynamic, but I assume that being external should not be a problem.
    Playing around, I now have the single computer on the ADSL line using a static IP once again, but would prefer that the ADSL modem/router? not work as a router, or be aware of anything other than the router being connected on the LAN side, allowing the router (WRT54GS) alone to handle touting.

    The ADSL modem uses PPPoE, and although uncertain, I feel that should not be changed. Essentially it appears that there is some option that disable the router function that should be used, and I'm not clear as to what I am looking for to change as there are so many setup pages and some setting pages are found from the page you are viewing.

    Additionally my WRT54GS router presently contains WAN info, related to the Satellite terminal's fixed IP, and Gateway IP, and the LAN setting of the router contains the static DNS IP addresses which are also found in the Satellite terminals setup. Some changes obviously need be made in the router as well so that it is no longer directly associated with either one of my internet connections.

    To disable routing on the ADSL modem, you should look for something like encapsulation mode, it should be on the same place where you set VCI and VPI values. Change that from whatever it was to something like bridge mode only. When you do that, the fields for username and password should disappear (to be handled by your WRT54GS router). Once you do this, all other setting on the modem such as firewall settings would become irrelevant.

    Currently the ADSL modem/router has all the necessary login/password info contained as does the satellite terminal. I need to keep the ADSL and the Satellite terminals ability to login into the ISP and allow the WRT to just perform routing from which ever WAN source is plugged into it.

    So just set your WRT's WAN side to DHCP or static IP, and plug it to your satellite or ADSL, and you should be all set?

    I believe I'm having a problem presenting my question clearly.
    I've been using the Satellite conected to the WRT serving 3 computers for a few years now. I am trying to now test a newly installed ADSL service using an Aztech DSL 605EU (ADSL 2/2+ ethernet/usb router) and the ISP installers were unable to figure out how to connect it to my router so they set it up connected directly to one of my computers. I am not using DHCP except for the ADSL WAN side, and I initially stumbled through setting up the router and got it to work by entering the WAN info from the Satellite box into the WRT's WAN info page. Right or wrong I don't know but it worked so I left it alone.

    Now I am trying to make what appears to require numerous changes simultaneously so that I can continue to connect all 3 computers to the WRT permanently, and have the ability to connect either the Satellite or the ADSL to the WRT WAN side without making any setup changes in any of the 3 pieces of hardware.
    The initial major problem is that both the WRT and the Aztech ADSL setup pages are currently accessed with the same IP (192.168.1.1), and I tried changing the Aztech's IP to 192.168.0.1 and cannot connect to it after saving the change. Using the one computer it it currently working with, I even tried changin the computers IP from 192.168.1.110 to 192.168.0.110 and then also changed the gateway from 192.168.1.1 to 192.168.0.1, and lastly also changed the DNS entry from 192.168.1.1 to 192.168.0.1 and still could not connect to the internet. The Satellite setup page is accessed using IP 192.168.0.1 and works with the router so I assumed the Aztech should be able to do the same as only one of the two connection sources would every be connected at a time.

    What I am trying to accomplish is:

    PC1:192.168.1.100 PC2:192.168.1.110 PC3:192.168.1.120
    | | |
    [ Linksys WRT54GSv4 Tomato FW 192.168.1.1 ]
    |
    [IPX5100:192.168.0.1] (OR) [Aztech DSL605EU:192.168.0.1]

    Without the need to change the setup in any device, simply swapping a cable.

    What is the WAN/Internet type on your Tomato set to?

    apinunt LI Guru Member

    The WAN/Internet type is set to static.
