I have a new fully updated server.
I ran so-allow and set it to a then used 0.0.0.0

That does not open the ports in the ufw checked with nmap.

If i run

sudo ufw allow 443/tcp

then 443 is opened correctly.

Chris,

Could you please clarify exactly the steps you took?

Are you trying to allow just port 443 from anywhere to your machine?

Thanks,
Wes

I tried 0.0.0.0 and 10.0.0.0 neither worked with the so-allow script using -a.

Chris,

so-allow does not currently support CIDR notation or allowing network ranges, however, invoking ufw directly does:

Ex. sudo ufw allow from 10.0.0.0/24 to any port 443

Is there any reason you want to open this port up to so many addresses?

Thanks,
Wes
