Pinging dynamic hostname internally resolves internally

    I have a WRT54G set up to update my dyndns.org hostname. Everything was fine until today, and I don't know what I did to change things.

    Basically my email client on my laptop is configured to use my dynamic hostname as the mail server (lets call it foo.dyndns.org). This worked fine (i.e. regardless of whether I was at home or not foo.dyndns.org would resolve to my external IP address). For some reason now it resolves to my internal address (i.e. pinging foo.dyndns.org gives me back 192.168.1.1, my router's address). This is no good for me because the WRT54G does not do portforwarding internally (so it won't forward my imaps port to the proper system on my network that is my mail server).

    Does anyone have any idea why this would happen, or any way I could force the WRT54G to resolve my dyndns hostname to my external address?

    Sounds like a loopback issue - try to disable it.

    If you man disable the DDNS updates, I did that already, then rebooted my router and laptop both but I still get the same thing.

    Nevermind...after getting to work and trying to connect, I realised that it's not that the address is resolving to the internal address when I'm home, but the router actually gave dyndns.org 192.168.1.1 as the external address of the router, so my hostname resolves to 192.168.1.1 from everywhere. I'll have to look at it when I get home tonight.
