Hi,

after putting privoxy on my router (openwrt) I noticed that the site is 
loading, but it never completes. At least after it hits the timeout, 
half of the pictures and parts of the HTML were loaded.

You were looking so much towards tcp settings, I turned off openwrt's 
QoS (even if I didn't thought it could have anything to do with it).

It fixed my issue. Connection reset is gone, the site is loading fast 
using privoxy on both my router and my VM.

As soon as I activate QoS, I get 'connection reset by peer' back.

My QoS settings are quite simple. Priorize UDP high and TCP normal.

I think I should take over to the openwrt team, and talk with them about 
that issue.

Cheers,
Sebastian
