Enhancement SSH via WWAN

[unclelez]

My sim card has a static IP, and I was hoping to be able to SSH into my router using it, but drop dear isn't configured to listen to that interface.

Are you able to add the WWAN interface to dropbear?

The existing dropbear configuration on the System screen only deals with the WAN interface. It shouldn't be too difficult to add WWAN s well.

I will have a look.

Hmm. It is a bit more complicated than I first thought. There are complexities with firewall rules if I just add another dropbear configuration for the WWAN interface.

It might be better (and much easier for me) to just give the option to use either WAN or WWAN for the external SSH connection.

Can you try this and make sure it works:

uci set dropbear.wan.Interface='wwan'
uci commit dropbear
/etc/init.d/dropbear restart

The other major concern that I have is that my understanding was that all mobile providers use CGNAT, so you might not be able to access it anyway...

Thank you, I managed to get both working in dropbear

Do you mean that changing the interface worked?
