Hi Peter. Thank you for your help.

I haven't installed apache web server in this linux box (it's in other
box).So, about the netstat command, the results is
-------------------------
oldprox3:/usr/local/squid/etc# netstat -anp | grep LISTEN | more
tcp        0      0 142.10.1.94:8080        0.0.0.0:*              
LISTEN      8834/(squid)
tcp        0      0 142.10.1.93:8080        0.0.0.0:*              
LISTEN      8834/(squid)
---------------------------------
Perhaps I must write a iptable's rule in order to redirect port 8080 to
8834?. So, if I've write this port and IP in squid.conf, I think it must
work, isn't it?. I write here the first lines of squid.conf,
---------------------------------------------
oldprox3:/usr/local/squid/etc# cat squid.conf|more
