No internetwith bridge interface



  • Hi

    I have here a problem with a bridged interface. I have two WAN ports (WAN1/WAN2) in a WAN group (WANGW), two LAN ports (LAN1/LAN2) configured as a bridge (LAN), a DMZ and a SYNC interface.
    The bridge is configured as described at https://www.infotechwerx.com/blog/Creating-a-Simple-pfSense-Bridge and https://forum.pfsense.org/index.php?topic=48947.0
    Now when i send a ping at the firewall trough LAN, it's not working. When i ping trough LAN1 or LAN2 it is working.
    Any suggestions why it isn't working?

    Below the network plan and some screenshots.

    What's the SYNC interface for? CARP/HA are incompatible with bridges.



  • Hi Derelict

    The SYNC interface is a seperate interface only for CARP.
    What do you mean incompatible? Even if the interface is not in the bridge?

    Best regards


  • Netgate

    SYNC interfaces generally have nothing to do with CARP.

    Please let us know what it is you are actually doing.



  • Hi Derelict

    I have an interfaced named SYNC for CARP. This interface ist just for the HA to the second pfsense.

    I try actually to get a connection to the internet trough the LAN bridge. The firewall itself has internet, but at the LAN port there is no internet. If i make a ping from the interface LAN1 or LAN2 it works, but not from bridge self (LAN). The network plan is in the first post, also the screenshots. The second WAN is not connected at the moment.

    Best regards

    It doesn't sound like you actually understand what CARP is so I still have no idea what you are doing.

    Running CARP VIPs and HA with a pfSense bridge interface is not compatible.
