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

#1
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.

RE: July CTP: Very fast on subnet, VERY SLOW (unusable) through router

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.
