Re: [SQU] Looks like a newbie problem:

Ok here it is, sorry it took so long, but I encountered a very strange
thing, and I am not sure if it is a squid problem,

I have a firewall configured so that nobody, but my IP address is allowed to
access the "squid" box.
But, somehow every time I access the proxy or the accellaretor, a ICMP
request come's from a router from the internet provider.
If I allow ICM from that router: No problem. If I block it: No data to my
Windows 95 IEX 5.5 client or my RH 7 Netscape client.

Must I concentrate on squid? Or on the OS?

PS Henrik, I will also trie a RH6.2 configuration tonight or tommorow night
