Port specific IP-range limitation rule

[sr71]

I'm not sure if this is at all possible, hence me asking here.

Need:
Set up a rule for port 10000 (just an example for this post) that will only allow connections to that port from a specific WAN side IP-range say  22.0.0.1 - 22.225.225.1 (just an example).

Other traffic and services happen on this same firewall and naturally they have their own rules.

Shouldn't be a problem.

1. Make an alias containing the allowed ip range
2. Create a firewall rule for WAN, port 10000 and source<your-iprange-alias></your-iprange-alias>

:o

So you can use Aliases on WAN side things as well?!
Cool!

And of course thank you!
