    I have a WRT54G v4 running the 11/11/05 v.23b DD-WRT connecting to Verizon Online DSL through a Westell DSL Modem.

    My previous router (BEFSR4100) would keep its IP address for a month or more before getting a new one. My new setup is renewing as much as once an hour.

    What could cause this? It is wreaking havok with my home-hosted email.

    Thanks in advance.
    (and Thanks to Brainslayer, I already made my donation for this incredible bit of software.)

    Re: 11/11/05 v.23b - Getting new LAN IP every hour or so

    We're talking WAN IP address right?

    "If" I happen to be getting the same IP address each time, is there a way I can tell the last time the router's IP was refreshed, to see if I'm having the same issue.

    I'm just wondering this, in relationship to a problem many of us were having, with at least Nov 7/8 firmware, where we'd get disconnected from the Internet every 3-5 hrs, with the router's inability to get a new IP address. I was asked by the ticket admin (Brainslayer?) why we'd be asking for a new IP address... which I didn't know.... I wonder if you're hitting upon the reason why...

    If this is a bug, make sure to report it on

    Thanks

    Correct. I was speaking about WAN IP.

    The good news is I went all night without a WAN IP change. I'll keep watching it

    Is seems that if I go into the web interface and make ANY change, no matter how small, the router gets assigned a new WAN IP. Is this the expected behavior? If no I will post a bug report.

    I just changed the TIME ZONE (with the Nov 11 beta) and it SEEMS that it is doing the same... but since it gives me the same IP, I can't be sure.

    The DNS servers disappear from the status page and the router LEDs, such as the Cisco Systems LED turns off and back on... So it SEEMS to be doing it. I don't know what type of reset it 'needs' to do when changes are made.

    I would suggest creating a bug report... If he says that it's normal, than fine. I would've created it, other than the fact I have no "proof" it actually got a new IP.

    Thanks

    Changing IPs

    Hiya, same thing occurs with 11/11 on my 54GS. Downgraded to 2.2

    Since I have not seen replies to this, I am going to assume that the new WAN IP acquisition after applying changes in the GUI is normal behavior. It has happened in all the versions for me up to 11/23.

    I must have asked a stupid newbie question or something.

    Just go to Administration -> Management -> IP Filter Settings
    and change value of Maximum Ports to 2048 and ... be happy :clap:
