WinXP PPTP MTU:1396

JoachimHummler
Hi,

when establishing a pptp-Connection over WLAN from a WXP-Client to ASTARO4.0X MTU-Size is always set to 1396:

ppp0      Link encap[:P]oint-to-Point Protocol  
          inet addr:192.168.1.1  P-t-P:192.168.1.2  Mask:255.255.255.255
          UP POINTOPOINT RUNNING NOARP MULTICAST  MTU:1396  Metric:1
          RX packets:1695 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1814 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:3 


because of this, I think, I'm not able to open http://www.gmx.net for example. The connection is very slow and almost 40 percent of the connections over Paket-Filter-Rules failed!
I've tried Dr.Tcp and similar, but now i think the WinXP PPTP MTU-Size is not changeable. Is this behavior becaues of an bug in ASTARO pptp or WinXP pptp?

Please Help!

    It's a Windows default.

    I think this is what you want:

    To configure Adapter MTU in Win2k+ : 
    [HKEY_LOCAL_MACHINE \SYSTEM \CurrentControlSet \Services \Tcpip \Parameters \Interfaces \{Adapter-id}]
    MTU = 1500

    Set it to what you think will be best...
