DDNS says "10.0.0.2" is Internet IP :-(

    This is not right of course... My Linksys router says my internet IP is 10.0.0.2. This is the IP that is given of by the DSL modem (a Netopia Cayman 3351EU-NGT). Now it updates my DynDNS account with this nonsense address.
    Can I get Linksys to see my real internet IP address?

    Thanks, Peter

    -If you're using Verizon DSL & PPP connection, your username or password in the PPP dialer is incorrect.

    That one is going to be tough. There's no way to bypass the Netopia and have the Linksys provide the credentials to the service provider's modem directly, and therefore get a REAL Internet address (and also eliminate the extra NAT hop)?

    You're going to have to look out one more "hop" to see your real Internet IP address (but from your comments I think you know that).

    Thanks, I more or less understand that. However, DynDNS' own DynDNS Updater util detects my external IP adress properly. Is this not possible within the Linksys?

    Yeah, I've checked that manual before. It seems our modem is quite customized, because there is no webserver at address 192.168.1.254.
    There is a webserver at 10.0.0.1, but that is in no way like the one shown in the documentation. I get 4 options: Username and Password (possibly to change my account?), Dis/enable NAT en Dis/enable DHCP. I tried both, but that didn't seem to help.
    I can telnet to 10.0.0.1, but again get something completely different from the manual. I don't get a CLI-prompt, but some Netopia setup menu with items Easy Setup, WAN Configuration, System Configuration, Utilities & Diagnostics, Statistics & Logs, Quick Menus and Quick View. I've been going through those menus before, but haven't found anything that seems to make much sense to me.

    Maybe you have some more suggestions for me?

    Thanks, Peter

    Forgot to mention, the website at 10.0.0.1 shows the logo of my provider, so the modem is clearly customized...

    This is JUST A GUESS. as I am not sure about this. but.....

    in the linksys gui config page. map to:
    Setup--> Basic Setup---> Network Setup(on the Basic Setup Page).

    In there you have a Router IP box. Within that is an option to enter a Gateway IP, would it be possible to enter your IP there and produce the result you are looking for?

    OR

    I thought (from the telnet access) there is a way to setup dyndns in your dsl mdm????

    again both are guesses.

    Thanks for the reply, ybbmadysu.

    I went into Setup > Basic Setup > Network Setup, and found the Router IP box, but couldn't find anything concerning a Gateway IP.
    I found something about Gateway under Setup > Advanced Routing, but changing that to "Routing" broke my internet connection.

    The modem itself doesn't have any DynDNS setup :sad:

    oops, forget to mention that my wrt54gs is using dd-wrt 23b2 12-25-05 firmware. (kick ass!!!).

    That might be the reason you dont have this.

    Before, I was using HyperWRT. was flawless. but changed to dd-wrt, wireless x-fers are a lil faster now.

    what firmware do you have?

    Look in the modem manual under Chapter 3 Expert Mode -> configure -> Configure for bridge mode. The instructions are there. This mode will pass the ISP connection directly to your router. Just set your linksys router to PPoE and put in a username and password. It should get the ISPs' address.
