howdy,
iptables will help u here for starters
/sbin/iptables -A FORWARD -s 192.168.x.2/32 -p tcp --dport 80 -j ACCEPT
/sbin/iptables -A FORWARD -s 192.168.x.2/32 -p tcp --dport 25 -j ACCEPT
/sbin/iptables -A FORWARD -s 192.168.x.2/32 -j DROP
similiar setup for the rest, this is not very clean though, might want
to create subnets for each network and put them in seperate network
cards in your linux box to physicly segment the networks, then you have
control

Example: 192.168.x.2 up to 192.168.X.45 to send emails and browse, while
the rest(192.168.X.46 to 192.168.X.254) to send emails only. How do I do
that?
