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.

Looking to create a Software RAID 1 setup for your 2-disk server on Ubuntu Server 20.04?

Screen Shot 2020-06-05 at 20 55 31

Let's start with the basics: the official guide by Ubuntu (https://ubuntu.com/server/docs/install/storage) is outdated/wrong. And as of March 2021 it's possible that there's a bug as well with how the bios_grub partitions are created when using multiple disks.

Now on to the solution:

  • Select "Custom storage layout" when you reach the storage configuration step of the installer.
  • If the disks have existing partitions, click on each disk under AVAILABLE DEVICES and then select REFORMAT. This will (temporarily) wipe out the partitions.
