FreeBSD 7.1 as a router - poor download speed, but normal upload
Hello everybody! Please help me if you can. I have a home server built on Gigabyte MiniITX motherboard with VIA C3 800MHz CPU and 512M RAM aboard. The server acts as a file server, torrent downloader, router and mail and HTTP server. I have a PPTP connection to my ISP through the integrated network card. The network configuration is: [0:04] kkur...@dot.kkursor.ru ~ # ifconfig rl0: flags=8843UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST metric 0 mtu 1500 options=8VLAN_MTU ether 00:19:cb:54:c6:15 inet 192.168.0.26 netmask 0xff00 broadcast 192.168.0.255 media: Ethernet autoselect (100baseTX full-duplex) status: active rl1: flags=8843UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST metric 0 mtu 1500 options=8VLAN_MTU ether 00:0f:ea:e2:cd:e0 inet 192.168.158.102 netmask 0xff00 broadcast 192.168.158.255 media: Ethernet autoselect (100baseTX full-duplex) status: active lo0: flags=8049UP,LOOPBACK,RUNNING,MULTICAST metric 0 mtu 16384 inet 127.0.0.1 netmask 0xff00 tun0: flags=8051UP,POINTOPOINT,RUNNING,MULTICAST metric 0 mtu 1500 inet 195.98.183.20 -- 172.30.96.1 netmask 0x Opened by PID 73795 tun1: flags=8010POINTOPOINT,MULTICAST metric 0 mtu 1500 rl1 is integrated network card and rl0 is an additional PCI NIC which is inserted into the only PCI slot on the motherboard. Connection to ISP is done over rl1 using port pptp-client. The problem is that there is very low download speed. My ISP provides symmetric 4Mbps line, but download speed is poor - about 1 Mbps. Upload speed is OK. I called ISP, they asked me to connect WinXP computer and measure speed. It was normal, therefore there is an issue in my server. If you could point me in the right direction, it would be wonderful. Thank you very much for your work!

With best regards and looking forward for answer, Kirill Sarksyan, Russian Federation Did you really saturate your upload while testing your download speed in WinXP? What you're describing is a common problem with how TCP works especially on (but not limited to) assymetric connections. I use the technique described by Daniel Hartmeier to circumvent it and can fully utilize my upload and download simultaneously. http://www.benzedrine.cx/ackpri.html /Morgan ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
