G/FBSD TCP Troubles

For those of you hanging out in #gentoo-bsd, you've probably
heard some
about my TCP problem on my Gentoo/FreeBSD box.  I discovered
the problem
because I was not able to checkout the Sunrise overlay.  At
first I
thought it was a problem with SVN, but I realized that I
simply cannot
make TCP connections to certain sites.

Then I suspected a proxy problem, but I had the same issues
both at home
(no proxy) and at work (transparent proxy), and other Gentoo
boxes at
both sites worked just fine.

What is really frustrating is its inconsistency.  I can
never connect to
 gentoo-sunrise.org, but at work two of the servers in the
distfiles.g.o
rotation were also inaccessible, as well as
packages.gentoo.org (and a
fair share of other random sites).

JoseJX suggested that it may be related to TCP windowing, so
I did some
Googling and found the following:

http://lwn.net/Article
s/92727/ <- An article on how this problem played
out in Linux.

http://lists.freebsd.org/pipermail/fr
eebsd-hackers/2007-January/019070.html
<- As described in the FreeBSD mailing list.

The sysctl workaround described in the FreeBSD mailing list
does not fix
my problem.  Also The_Paya suggested a packet-filter
approach which has
not worked as of yet.

So anyhow, I am making due, but it is a frustrating problem
to say the
least.  Any suggestions are greatly appreciated.
