LAN Interface makes WAN not receive address from ISP



  • I seem to have been faster on the writing then on the searching. Seems to be the same problem then this :
    https://forum.netgate.com/topic/135920/pfsense-2-4-4-fails-all-pppoe-s-after-disabling-one/21

    I find myself in a very weird situation. Last week a tech from our ISP came in to take care of some things and we had to be disconnected for a while. One of the things was configure a static address (I don't see how that would be a problem but we never know).

    Since that disconnection, every time I change something on one of the LAN interface the WAN loses connection with the ISP.

    WAN is connected by PPPoE to the ISP, it receives a static (dynamic before that) IP address.
    LAN is just that, a LAN. I have 3 of these and, for now, only one seems to cause the problems. I have yet to test the other ones as this is in production and the one I habitually make tests with is the one causing trouble.

    To that test interface is connected another PFSense machine (the testing environment router) and since that day, when the ISP tech came, it does not connect to its WAN (the trouble interface) at all. I've tried it with DCHP and static and every time I make a change to the main router, general internet failure everywhere.

    So this is pretty much a two in one:
    Router #1 stops receiving internet from ISP if I play around with the "testing env" interface
    Router #2 does not receive internet from its WAN that is the "testing env" interface

    PFSENSE 2.4.4-RELEASE on Dell PowerEdge R610
    VLAN 35 for the WAN (Cannot change, it's how the ISP works)

    The fastest way to make the WAN work again is to change the LAN network port to another one and then back to what it was.

    Here are some logs when it did not work :
