small question, but the vast topics,

 do you want to make your linux box just as a router for internet surf, for
lan.
if so you have to enable the packet forwarding capability in linux
just vi /etc/sysctl.conf

# Controls IP packet forwarding
net.ipv4.ip_forward = 1 (here originally 0)

then you have to run NAT(Network Address Translation).
(I have already sent you the link http://netfilter.org)

briefly, for eg. your public IP address:203.79.37.100/24
and your LAN is 192.168.0.0/24


Just note that there are two types of NAT
SNAT (source Nat)
DNAT(destination Nat)

for your scenario you have to use SNAT.

just run as root the following commands.

iptables -t nat -A POSTROUTING -p tcp -s 192.168.0.0/24 -o eth0 -j SNAT --to
203.79.37.100

(note that eth0 is your outgoing interface connected to the internet)

then you can visit the internet through the LAN, provided DNS, gateway etc
are properly set.


you may also use Linux as a proxy or transparent proxy through squid.(see
squid.org)
