But I have an interesting observation. The gateway freezes very quickly, = if torrent client programs are running on workstations. I assume the cause of the problem consists in many number of TCP/IP = connections that torrent client establishes. Any ideas? Maybe I can tune somehow a TCP/IP via kernel, sysctl or pf settings? > There is one FreeBSD server in our company. The server platform is: = Supermicro SuperServer 6014V-T2B (2x Intel > Xeon 2.8, 1Gb RAM, 3WARE = 3W-8006-2LP RAID-Controller). > The server works as: > - a gateway between LAN and Internet > - an Intranet web- and database server (Apache + MySQL + PHP) > - a firewall (OpenBSD pf) > - a transparent proxy server (Squid) > A mounthly traffic through this server is about 100Gb.
