[squid-users] Problem for use Squid with Interscan VirusWall Web

Hi,
I use actually a squid proxy, and I want add a virus scanning
fonctionnality.

I use 2 Linux boxs, Squid on 10.202.17.10 with port 3128 and Interscan
on 10.202.17.11 with port 8090.

So, I add the following lines in squid.conf :

cache_peer 10.202.17.11 parent 8090 7 default
prefer_direct off

And Interscan configuration is :

InterScan HTTP Proxy port (connects to browser): 8090
Original HTTP server location:
        Other (server and port): 10.202.17.10 3128
        
But Squid said respond :

1007632350.684 4383 10.202.17.10 TCP_MISS/200 18814 GET
http://intrinsec.com/fr/body.htm - TIMEOUT_FIRST_UP_PARENT/10.202.17.11

......

That is when the firewall block all packets from 10.2002.17.10.
If I permit Squid to go to Internet, the Squid try parent
(TIMEOUT_PARENT) and go direct.

How to do work corectly Squid and VirusWall together ?

Thanks in advance
