We have a squid proxy on the cloud with IP Address 50.x.y.z listening on tcp port 3128 and running in transparent mode. This proxy server is running Debian 6.0 and is located at a data center.
In our office we have a Cisco router with Public IP 203.x.y.z/29 and private IP 192.168.1.1/24. The Local LAN network is 192.168.1.0/24. I have allowed the public IP 203.x.y.z/29 in the squid.conf file and hence the LAN users can browse internet using this squid proxy. I would like to know if it is possible to transparently redirect all web traffic to the squid server running at data center ??
Please note that I am fully aware of the fact that this can been be done using route map or WCCP if I had a proxy server in the LOCAL LAN and also that I can use WPAD for automatic proxy detection but I want transparent redirection.
