Hello,
i searching for a why or the MTU-problem. Somebody have any idea to do this?
Before we have Kerio we have Linux server, now we chance to Kerio and have Problem with Online Banking, Windows Updates and more.

But i don't to chance on 120 Computers the MTU, that's uncool.
I know, with a MTU size of 900 or 1400 all will be work.


We're using Kerio 6.0.9 with the CFOS DSL Driver, 3M/bit DSL, running on windows xp.

thanks for help!

use this
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\ Parameters\Interfaces\[Adapter ID]]Value Name: MTU

I you use a DHCP server you can specify the MTU for a DHCP client. If you use the KWF DHCP server check the Advanced... button at the options window.

Hello,

I set the MTU in the Windows2K3 DHCP-Server. But it dosn't work.
When i change it dircet in the Computer in the reg, it work.

I like to have a script work the logon what chances on adapters to 1400, i think that's the best MTU.

thanks,

Dustin

Just changing it in the DHCP server is not enough. You have to wait for the client to get a new lease.

New lease?
i make all configurations in the DCHP before the clients get a IP-Adress.

I think that's not the problem.

But i don't know why we have this problem with Kerio and not with Linux?

There must be a way without touching the MTU.
