My home network consists of several computers sharing a DSL internet connection. All computers run Gentoo linux with kernels 2.6.25 - 2.6.27.
I have an extremely frustrating problem that I have been unable to track down: I can connect to most web sites, but not all. Some sites load partially or never even connect. When I try to access the site from another location (work, friend's house, etc) then I don't have any problem.
I thought that maybe the firewall was the problem, so I flushed all the rules in the filter and nat tables (except for the MASQUERADE rule) but that had no effect on the symptoms.
The fact that some web sites work and other sites do not work makes me think that something about my TCP/IP system isn't playing right with some other routers. This article sounds similar to what I am experiencing: http://lwn.net/Articles/92727/
, but disabling TCP window scaling (on the router and on the clients) does not fix the problem.
The sites that I have noticed this problem with:
