[arm-allstar] Adding IP table rules so only my SIP provider can connect to my node (stop hacking attempts)

[Vendel]

Hi Doug, based on my “ipconfig /all” wireless setting response obtained via my laptop, what would my subnet be?
Wireless LAN adapter Wi-Fi:

Is it 192.168.1.1? I just want to be sure I get this right. Thanks again, Vendel/ K2DSI.

Also in my example you also need to change the local subnet to yours. In my
case it was 192.168.0.0  - but your is probably different.
