Asunto: [Koha] Sort of OT: configuring UFW

My apologies for posting a question that's not exactly Koha-related, though could be. I'm hoping that someone here can explain in a way that a simple medical librarian and part-time Koha geek can understand, or point me to a source that can. Yes, I checked the man page.

What I want to do us use UFW (Uncomplicated Firewall) on Ubuntu to allow access to only permitted IP addresses. I can add one IP address without a problem:
   sudo ufw allow from 192.168.1.115 to any port 80

I think I know how to add a range consisting of anything beginning with 192.168.1.*:
   sudo ufw allow from 192.168.1.0/24 to any port 80
(Please correct me if I'm wrong.)

What I need to do is allow access from the range
   192.168.*.*
or something like this
   192.168.22-65.*
or 192.138.187-189.*

Any ideas or sources of information?

Thanks,

--Fred
