Help!! WAN DHCP is not working trough my ISP router as bridge pfsense



  • Hi, I tried to configure the my ISP Netgear router SW as bridge, but when I tried to set up the interface wan by DHCP I didn't get a correct IP. it took 0.0.0.0 and the default gateway in the range of the 192.168.0.X. I tried to configure the wan interface static, and assign it inside the range of my IP Public (73.124.X.X) when I assigned this I tried to do ping or tracertroute to 8.8.8.8 but nothing responded. Please any ideas?

    So you just took an IP, belonging to your ISP, that is probably assigned to a fellow-client, and you tried to use that.
    ( while doing so the connection of this fellow probably also died ).

    It could be anything.
    First, look at the paper from your ISP that explains how to set up a typical router device as a bridge.
    Does your connection actually accepts bridging devices ?
    If so, is standard "DHCP" as described in the RFC used ? Or did your ISP use some "home made protocol" by adding DHCP "options" that the client should sent ? Etc.

    A know issue us : when the WAN NIC, from a pfSense point of view, comes up, the DHCP-client is fired. But to early, the bridge isn't build yet, and you obtain some RFC19819 IP.

    This :

    InterfacesWAN (driver) > DHCP Client Configuration > Options = Advanced Configuration

    can be used to solve timing issues, or to exclude RFC1919 answers, etc.
