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.
