PfSense gets WAN IP, but no internet

  • Hi,

    I've been using pfSense for a while now, but I'm not very skilled when it comes to the actual technical side of how it works.

    I'm not sure in which forum to post this, as my problem occurs in both 1.2.3 and 2.0beta.

    My network is set up with a Dynalink RTA1320 in half bridge mode, connected directly via ethernet to my dual NIC pfSense box. This is then connected to a switch on the LAN side, and subsequently to a bunch of pc's. pfSense is running a completely stock configuration.

    I have a problem, in which my pfSense box will get the WAN IP, but does not appear to be able to access the internet. Pc's on the LAN side can't access websites, or ping IP addresses (thus, I think, ruling out a DNS issue). The pfSense box can ping LAN IP addresses, but no external IP's or hostnames.

    The problem generally occurs when the ADSL connection goes down and then comes back up, or if I unplug the cable between the RTA1320 and pfSense. Rebooting pfSense normally fixes the issue.

    Recently though rebooting has not fixed the issue, which is why I'm posting this.

    If I plug my laptop directly into the RTA1320, the laptop acquires the WAN IP, and can access the net perfectly.

    I've experienced this problem at 3 different houses, on 2 different versions of pfSense, on 2 seperate boxes, and I've tried using 2 different modems. This all seems to point to a configuration issue that I'm overlooking.

    Any ideas? More info? I'm not entirely sure what I should be telling you. Thanks in advance!

  • Can you post your rules and logs in the states window?

    Waht packages have you instaled?

  • This is a completely stock setup, I reinstalled pfSense last night as a last attempt to fix it. So no extra packages, and no rules. I'll get the logs when I get home from work.

    Some people have had problems before with half-bridge modems, because certain models behave erratically when it comes to passing off the public IP by DHCP.

    Why not just fully bridge it and let pfSense login with PPPoE?

  • I'm not sure that the modem I'm using will let me. I'll do some more research on it.
