Limiting open port RST response from 247 to 200 packets per second

[Alex Dehaini]

Hi Guys,

I have some issues with Squid on Freebsd. 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

When I stop Squid, everything returns to normal. Any idea what is causing
this. I will appreciate any help.

Thanks
