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......
