I have setup a pfsense box with dual WAN
following tutorials it all works fine, even got proxy running :) great stuff!!

I have WAN1 with unlimited but slow during peak hours, (3pm-11pm)
I have WAN2 which is 4G mobile Data and its fast all the time

I only have 30GB per month and need to restrict what uses it…

I hope to get some guidance as to how to enforce restrictions on the WAN2 so it doesnt waste my fast internet on stupid updates and other crap...

thanks
Shaun
