Not working auto-renew at DHCP

Gerald Schuh1

Hi,

I'm using an Huawei Modem with LTE on wan1.

The Sophos XG receives the IP via DHCP.

Everytime when there is an IP renew it fails and the interface (wan) is offline until I login to the firewall and click on save in the interface config menu.

I'm using V19.

As I read this issue isn't new.

Did anyone find a solution which fixed this issue?

    Hello ,

    Thank you for reaching out to the community, So the WAN interface IP assignment is set to DHCP right ?
    And how frequently the interface goes offline ?

    Whenever it goes offline, can you try the following cmd from the device console:
    console> system diagnostics utilities arp ping interface Port<no> <gateway ipaddress>

    And if this works, and brings the interface online, then it could be possibly an arp issue. 

    Please confirm so that we can plan the next plan of action !!

    Thanks & Regards,

    Actually it is every day at the same time. (this time the ip gets renewed ).

    Yes the WAN interface IP is assigned via DHCP.

    Next time, when the interface goes offline I will run the command from the console.

    Maybe I should use the api as a workaround to solve it.
