    July CTP: Very fast on subnet, VERY SLOW (unusable) through routerand to Linux box


    A coworker and I have the July CTP of Vista installed.
    Connections to servers on the same subnet are very,
    very speedy.

    However, when we try to connect to anything through
    our router, the connections are unusably slow. The
    same goes for connections to a Linux server with a
    rather aggressive configuration of Netfilter (via
    iptables).

    I find a post ("A painful Vista networking bug",
    http://blogs.zdnet.com/Bott/?p=10) that seems to be
    related, but I can find little else.

    I had a problem like this .. made the hubby take a look... in vista it give
    you the 6 and the 4 internet protocol both checked by default in the network
    properties panel.. he just disabled the six and put the ip address info in
    the 4 and it flew. Dont know if this will help ya but it did for me.

    Thanks, but no, that didn't help. We tried some pretty
    severe paring down, unchecking everything that wasn't
    absolutely necessary, turning off the firewall, etc.
    No luck so far.

    I've had issues with the windows firewall and linux MTU setting before, and
    this kind of sounds similar to that. At home I have a linux firewall and it
    does some fancy traffic shaping and such so I can 'promise' traffic and
    latency for certain 'important' things like battlefield2. I also have a
    gigbit switch that supports jumbo frames. The combination of jumbo frames,
    the windows firewall and the linux firewall/traffic shaping, didn't do so
    hot. If I wanted to have the windows firewall on I had to disable jumbo
    frames on the switch, and lower my MTU on the linux box to 1400... Because
    you are going through a router to your linux box, I would bet you are
    experiencing something similar. try disabling the windows firewall...

    Can you tell me what build of Vista are you running ?

    Are you seeing slow speeds during file transfer or is it a general
    networking issue. If it is a general networking issue, it might be useful to
    post this in microsoft.beta.longhron.networking.tcpip group since this might
    some tcp tuning issue. A network capture when you are observing slowdown
    will be helpful.

    Build 5472, the July CTP.

    It seems to be everything. Web browsing, ssh connections,
    Remote Desktop . . .

    I don't have access to microsoft.beta.*, but I'm an MSDN
    subscriber, if that matters.

    I can try to work on a packet capture. What I'm hoping to
    do is get two: one for a connection from behind our router
    at work, and one from home.
