Pfsense PPPoE no Internet after dropout even though it gets IP Address



  • Hey guys, So basically I have this problem that other people also seem to have with pfsense. I have my billion 7800NL modem in bridge mode giving pfsense the PPPoE authentication. Everything works and is fine until my modem either drops connection, manually disconnected or restarted. Pfsense does the job of getting the new IP address but no internet connection.

    Rebooting pfsense doesn't seem to fix it, it just gets a new IP address and wont allows Lan to access internet.

    Does anyone know how to fix this problem?

    thanks :)

    Are you getting a connection on the pfSense box itself? Can you ping sites from Diagnostics > Ping?

  • Pfsense obtains a new IP, my ISP's website shows me that pfsense has the new IP but trying to go to google.com or any website times out. I ahall check the ping from pfsense itself right now.

    Sorry for the long wait. Pfsense is now having trouble getting a stable PPPoE connection, it keeps dropping. I did manage to try and ping but was unsuccessful, I can see in the firewall logs that all local IP's are failing to connect "cannot resolve" the connection.

    Hmm, you're seeing the traffic blocked in the firewall log?
    I assume you have rules on LAN to allow it?

    If you can't ping from diagnostics then there's no chance of accessing anything from LAN.
    Check the ppp log.
