Hi,

I have a serious problem with my network.
I have connected 2 PC's, 1 - FreeBSD, 2 - Windows XP.

The problem is follow - My FreeBSD limmiting connections , I cannot open
more 224 TCP4-Sockets in my Windows Box.
When I downloading torrent file, I cannot create more connections to the
web, and while this time I can't open for example - web sites.

Tow problem who worry myself is when I scan a my freebsd box or other
"server" for open ports its FAKE show me: 81 82 ,83 ,465,463 and other ports
open.. but It's FAKE .. it's not really open..

I Cleared my sysctl, and test, cleared my firewall and test, re-build my
kernel with any options changed and test again.. Just don't Work :((

I have use PF firewall and FreeBSD 6.2-RELEASE-p5.

I Think this problem is from "net.inet.tcp.blackhole=2" in my sysctl because
it's work before i do sysctl -w net.inet.tcp.blackhole=2..
but when back this option to value = 0 this problem is stay there.. and no
restarts or re-build my kernel can fix this..or maybe be wrong to
this supposition. Sorry for my english.

Thanks in advance.
