Assunto: New Squid Server 3.5.20 on Centos 7 - Trying to redirect local web access to Port 80 on Linux Servers with iptables to Squid Server with http_port intercept
Hi Squid Jedi´s,
I am just a little stuck tryng to replace an old Squid 3.1.23 Server on Centos 6 that i use to redirect local web access to port 80 on linux servers to Squid Server.
On my Squid 3.1.23 Server on Centos 6 i use http_port 3128 transparent mode and on my Linux servers clients i use iptables to redirect Web traffic as below ( this config works ):
Squid Server 3.1.23 :
