DDNS in AP mode Possible?

    I am running my parents WRT54G as an Access Point ONLY (i.e. WAN / Internet option is Disabled) as Qwest DSL requires that their modem be the gateway. When I go configure DDNS (I'd like to use DynDns.org) I notice that it lists the external IP address as Is there a way to configure Tomato so that it knows what the external IP address is (even though I'm plugged into the LAN ports and not using the WAN port)....many Webpages, Dynamic DNS Apps, etc... can do this, why can't Tomato?

    Thanks in advance for your reply.

    installing ddns client on the computer is the easiest..

    It may be the easiest, but I'd like to keep my Dynamic DNS name current, even if my PC is down for extended periods. There must be a way to do with Tomato....either a new version, or through telnet commands....anyone?

    you'll have to set external nvram variable wan_ipaddr via script at startup and then you could use the GUI built in DDNS client maybe something like this at the firewall script
    that URL returns the current IP address this is one possibility or creating a new nvram value based on a site like this and copying it over to wan_ipaddr or manually running ezupdate via cron and then you need no nvram values only a little parameters.

    Is this gateway possibly a NAT router that gives you a LAN IP or is it passing the WAN routable IP address to the computer via the Tomato AP ?

    See if the modem/gateway has a DynDNS update, otherwise your going to have to create you own update that will allow you to update the IP....
