UTM settings on WAN port cannot be changed

stegman

When i change the MTU valua on my WAN interface from 576 to 1500 it will fall back to 576 after a while.

Is this normal behavior or do i have to perhaps try to set this on my DSL modem?

    Hi again,

    I have tried that but i lose the internet connection.
    In the GUI it is possible to edit it to 1500 and it stays that way but the internet connection is lost.

    My file looks like this:
    interface "[<INTERFACE>]" {
    timeout 20;
    retry 60;
    script "/usr/sbin/dhcp_updown.plx";
    request subnet-mask, broadcast-address, time-offset,
    routers, domain-name, domain-name-servers, host-name,
    domain-search, nis-domain, nis-servers,
    ntp-servers, [<INTERFACE_MTU>];
    [<HOSTNAME>]
    }

    I have tried several things;
    Only removed the INTERFACE_MTU
    Also removed the <> brackets
    Completely removed [<INTERFACE_MTU>]

    The setting keeps his value but internet connection is gone, and also restoring the file to its original stat will not
    restore the connection, i have to restore from a backup....

    Strange behaviour for me.....

    after several tries it works and the file currently in use looks like this:

    interface "[<INTERFACE>]" {
    timeout 20;
    retry 60;
    script "/usr/sbin/dhcp_updown.plx";
    request subnet-mask, broadcast-address, time-offset,
    routers, domain-name, domain-name-servers, host-name,
    domain-search, nis-domain, nis-servers,
    ntp-servers,;
    [<HOSTNAME>]
    }

    I tried this one earlier but did not work, not sure what i did wrong......
