In general, you're nobody forbids specify one visible from all networks
IP address / network interface, define a proxy on it and use WPAD / PAC
to configure clients by means of DHCP / DNS.

each network and all clients will be going through it.  Now these are
CentOS 6 servers, not workstations.  I need all servers in each network
segment to go through the proxy so traffic can be monitored for each
network.  Now would a transparent proxy help?? Hope this make sense.
