      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
