$ iptables -t nat -A POSTROUTING -s @priv -o eth1 -j SNAT --to-source @pub. If the packet is coming from @priv, let's put it on our output interface eth1 and jump to the Source Nat Protocol that will modify the packet so it has the public address (@pub) as source. Here! You did it. One private IP address mapped to one public IP address. Dynamic

$ iptables -t nat -A POSTROUTING --destination 10.0.0.1/32 -j SNAT --to-source 10.0.0.160 2. Using a static route. Alternatively, instead of an iptables rule, add a static route for the destination host to the routing table, using the following syntax: $ ip route add /32 via src Quick-Tip: Linux NAT in Four Steps using iptables # /sbin/iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE # /sbin/iptables -A FORWARD -i eth0 -o eth1 -m state --state RELATED,ESTABLISHED -j ACCEPT # /sbin/iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT You should now be NATing.

Jan 28, 2020 · This table contains NAT (Network Address Translation) rules for routing packets to networks that cannot be accessed directly. When the destination or source of the packet has to be altered, the NAT table is used. It includes the following chains: Prerouting – this chain assigns packets as soon as the server receives them.
