-===== IP Forwarding =====
-To enable a machine to act as a gateway for a network:
-  echo "1" > /proc/sys/net/ipv4/ip_forward
-  iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -j MASQUERADE
-Where 192.168.1.0/24 is the network which will use this machine as a gateway.
-To make this permanent, on Debian/Ubuntu:
-  touch /etc/network/if-up.d/iptables
-  chmod 755 /etc/network/if-up.d/iptables
-And add the following the new file:
-  #!/bin/bash
-  echo "1" > /proc/sys/net/ipv4/ip_forward
-  iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -j MASQUERADE
-For Red Hat/Fedora:
-  iptables-save
