I am running FreeBSD release 4.9 and Squid version 2.5. I have setup FreeBSD as a bridge so that all traffic from my network can transparently pass through the FreeBSD server. I am running Squid on the same server and I created an ipfw rule to redirect port 80 to port 3128. Normally, when Squid is not started - we see traffic close to 30MB flowing through the server. Immediately I start squid, the traffic drops to half and sometimes lower and stays there. When this happens, I have a lot of clients that will call and complain they can't access the Internet. At the same time, I get these log messages *Feb 5 20:39:44 myserver /kernel: Limiting open port RST response from 247 to 200 packets per second Feb 5 20:39:44 myserver /kernel: Limiting open port RST response from 247 to 200 packets per second Feb 5 20:39:45 myserver /kernel: Limiting open port RST response from 239 to 200 packets per second Feb 5 20:39:45 myserver /kernel: Limiting open port RST response from 239 to 200 packets per second Feb 5 20:39:46 myserver /kernel: Limiting open port RST response from 273 to 200 packets per second Feb 5 20:39:46 myserver /kernel: Limiting open port RST response from 273 to 200 packets per second Feb 5 20:39:47 myserver /kernel: Limiting open port RST response from 228 to 200 packets per second Feb 5 20:39:47 myserver /kernel: Limiting open port RST response from 228 to 200 packets per second Feb 5 20:39:48 myserver /kernel: Limiting open port RST response from 225 to 200 packets per second Feb 5 20:39:48 myserver /kernel: Limiting open port RST response from 225 to 200 packets per second Feb 5 20:39:49 myserver /kernel: Limiting open port RST response from 244 to 200 packets per second Feb 5 20:39:49 myserver /kernel: Limiting open port RST response from 244 to 200 packets per second Feb 5 20:39:50 myserver /kernel: Limiting open port RST response from 259 to 200 packets per second Feb 5 20:39:50 myserver /kernel: Limiting open port RST response from 259 to 200 packets per second Feb 5 20:39:51 myserver /kernel: Limiting open port RST response from 234 to 200 packets per second Feb 5 20:39:51 myserver /kernel: Limiting open port RST response from 234 to 200 packets per second Feb 5 20:39:52 myserver /kernel: Limiting open port RST response from 243 to 200 packets per second Feb 5 20:39:52 myserver /kernel: Limiting open port RST response from 243 to 200 packets per second Feb 5 20:39:53 myserver /kernel: Limiting open port RST response from 218 to 200 packets per second Feb 5 20:39:53 myserver /kernel: Limiting open port RST response from 218 to 200 packets per second Feb 5 20:39:55 myserver /kernel: Limiting open port RST response from 233 to 200 packets per second Feb 5 20:39:55 myserver /kernel: Limiting open port RST response from 233 to 200 packets per second Feb 5 20:39:56 myserver /kernel: Limiting open port RST response from 241 to 200 packets per second Feb 5 20:39:56 myserver /kernel: Limiting open port RST response from 241 to 200 packets per second Feb 5 20:39:57 myserver /kernel: Limiting open port RST response from 220 to 200 packets per second Feb 5 20:39:57 myserver /kernel: Limiting open port RST response from 220 to 200 packets per second Feb 5 20:39:58 myserver /kernel: Limiting open port RST response from 206 to 200 packets per second Feb 5 20:39:58 myserver /kernel: Limiting open port RST response from 206 to 200 packets per second Feb 5 20:40:01 myserver /kernel: Limiting open port RST response from 223 to 200 packets per second Feb 5 20:40:01 myserver /kernel: Limiting open port RST response from 223 to 200 packets per second* When I stop Squid, everything returns to normal. Any idea what is causing this. I will appreciate any help. Thanks -- Alex Dehaini Developer Site - www.alexdehaini.com Email - alexdehaini@gmail.com
