Hello Squid friends!

I've setup a transparent proxy with Squid2.2STABLE2 routing access from a
Cisco router.

It is working, but if I do a "tcpdump -n proto ICMP" at that Linux/Squid
machine, I get many, many, many lines like this:

17:29:15.094150 200.231.197.10 > 200.231.148.156: icmp: 200.240.10.51 tcp
port 80 unreachable [tos 0xc0]
17:29:24.354342 200.231.197.10 > 200.231.148.158: icmp: 200.245.232.12 tcp
port 80 unreachable [tos 0xc0]

200.231.197.10 is the Linux/Squid box
200.231.148.156 and .158 are my dial-in user
200.240.10.51 and 200.245.232.12 are the destination web server (the site
the user is probably visiting)

I get *lots* of this line only in a minute. And because of this, the
access is perhaps slower with squid than without squid.

I've read the cineca.it squid archive, and altough I found a couple of
messages regarding this issue, I couldn't resolve my problem.

Is there a cure?? ;-)

Thanks!
