[squid-users] squid <-> trend micro viruswall

Hello,

In my company, we use in our DMZ squid and the product trendmicro viruswall in
the following way.

corp. network <-> Squid <-> viruswall <-> Internet

The proxy squid listening on port 3128 and viruswall listening 3128 for HTTP
traffic and port 21 for FTP traffic.

HTTP request <->squid 3128 <-> 3128 viruswall <-> Internet
FTP request <-> 21 viruswall <-> Internet

Today traffic HTTP crosses by squid and then viruswall by port 3128, But
traffic ftp crosses only by viruswall on port 21. Thus with this system I
loses the benefit of the cache.

goal :
I would wish to say to squid to use port 3128 for the HTTP traffic and port 21
for ftp traffic.

HTTP request <->squid 3128 <-> 3128 viruswall <-> Internet
HTTP request <->squid 3128 <-> 21 viruswall <-> Internet

Have you an idea!

Thank you in advance.
