well dear thats a iptables issue if u are using linux.(as u mentioaned about
linux care)
we normally do this to make transperant proxy
e.g
iptables -t nat -A PREROUTING -p tcp -s 192.168.100.0/24 --dport 80 -j
REDIRECT --to-port 8080
or normally on firewall

iptables -t nat -A PREROUTING -p tcp -s 192.168.100.0/24 --dport 80 -j DNAT
--to squidbox:8080

now u want pc 192.168.100.23,33 to not go into proxy

use this command

iptables -t nat -I PREROUTING 1 -p tcp -s 192.168.100.23 --dport 80 -j
ACCEPT
iptables -t nat -I PREROUTING 2 -p tcp -s 192.168.100.33 --dport 80 -j
ACCEPT
iptables -t nat -I PREROUTING 3 -p tcp -s 192.168.100.0/24 --dport 80 -j
REDIRECT --to-port 8080
