To set up static route on Linux machine use following lines in the static-routes file in format shown below:

network-interface net network netmask netmask gw gateway

3. iptables

iptables is the current fedora and Linux enterprise default firewall.

It implements ipchain rules as a part of its firewall filtering, iptables and ipchains can’t run at the same time.

/etc/sysconfig/iptables is a file where we can store iptables and ipchains rules.
