easyrule command documentation should document permissible wildcards
At https://docs.netgate.com/pfsense/en/latest/firewall/easyrule.html#easyrule-in-the-shell the documentation is typically terse. But documentation should not be for those who already know things, but for those who know nothing.
The entire page there does not make one mention of what wildcards are permissible.
With trial and error (because I had the specific need) I ended up figuring out that
easyrule pass wan any any any any
works, but would
easyrule pass any any any any any
also work? Don't know, wasn't in a position to risk my setup playing aroud with it. And frankly, nobody should be having to do trial and error, one should be able to read the documentation, and know what, if any, wildcards are applicable for each parameter to the command.
