Captive Portal suggestion
I face a problem with captive portal where, for some reason, the rules was not apply to the ipfw and redirect was not worked, leaving the navigation "free".
When executed the command ipfw show, i got a error in the console (get_sock). After re-save the captive portal setting, the command was successful executed in console return all tables and rules. Including the ipfw_load and dummynet_load in loader.conf.local solve this problem.
I'm testing in a Alix board with many rules. Maybe is not better loading this modules by loader.conf ?. For slow devices can avoid problems like this.
ATM after an upgrade or a re boot you need to click save on the CP page.
So, loader.conf is not the definitive solution ?.
