Some examples of SNAT, DNAT with iptables with comments

mainly used in start-up script

How to test 'safely'

When we play with iptables aka firewall we might end up in situation, where we execute rule, which has unforseen impact - lock yourself out. Recovering from this situation is necessity.

How to:

• Enable reboot via SMS.
• Test all commands in shell first before putting them into Start-up script. This way the command will be wiped out, when unit is rebooted.
