Hello, You can take a look at iptables charm. It does the "easy part", that is admin defined ruleset.
I was actually thinking of making it also use the open ports. I'm pretty sure juju-info relation has the open ports data, but I can take a look.

The "easy" thing to do is provide a config block and have admins write in rules and just apply them. I was wondering though, if I wrote a subordinate charm on juju-info to attach to anything, is there any mechanism for me to find the exposed port of the parent charm? and whether its exposed or not?
