examples of SNAT, DNAT with iptables for Advantech, Conel routers, with comments (probably will work on other routers where iptables can be manipulated, care needs to be taken on applying these commands after reboot).

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.

# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.

# Once you're done here, go to

# to learn SOOOO much more.

// This started as a tweet with a joke of "C++ pro-tip: #define private public",
