All WANs down at the same time



  • Hi everybody,

    we have three roads to the internet:

    | Interface Name | Gateway Name | ISP | Type of connection |
    | WAN1 | GW_WAN | Telekom | vDSL25 |
    | WAN2 | WAN2_PPPOE | Telekom | vDSL25 |
    | LTE | LTE_DHCP | Telekom | LTE |

    Last night all three connections broke off at the same time. The logs look like this:

    About three hours later WAN1 and WAN2 came up again automatically:

    LTE didn't come up automatically, but after a reset of the modem, it worked.

    Now I like to find out whether this was a problem at our ISP or inside our firewall. Do you have any thoughts or suggestions on this?

    Thanks a lot and many greets
    Stephan
