local: ns1.asuscomm.com: bad variable name

[WulfgarCA]

Hi there,
I had the following error:
./ASUSddns.sh: 28: local: ns1.asuscomm.com: bad variable name

after googling a bit I found this:
"local" is a bash-specific feature which is not defined in the POSIX standard for sh (the POSIX shell).

after changing the top of the script to #!/bin/bash everything works fine.
I am running Ubuntu 19.10 and just wanted to give this as a feedback if someone else has the same error.

Thanks for the great script!

P.S.: My Mac address was stored in "et2macaddr" and not "et0macaddr" as mentioned in the docu.

I'm using /bin/sh because this script is often used on embedded devices where there is no bash

Anyway thank you :)
I'll add both info in the readme
