I am able to get NAT to work using the following snat rule:
iptables -t nat -A POSTROUTING -o em2 -j SNAT --to 192.168.2.2
My question is: Why is this rule not displayed when I issue the command:
iptables -L
or even
iptables -L -v
iptables -L -t nat
is what you're looking for.
As you specify the table when you add the rule, you have to specify it to see it.
