So I was thinking of the backup WAN functionality. I wonder how the average person affords such a thing.

That said, there is a service out there that is basically very very low cost LOW USAGE 3G/4G functionality. The only thing is if I have a Torrent running, and I am not home, I don't want that thing burning through my data.

Is there any good way on a PC to prevent that, and more importantly is that something planned for the backup WAN where you can have alternate rules???
 
No idea what are Asus's plans regarding Dual WAN. On my end I have no plan on changing the current implementation.

I use the wan-start and firewall-start events to only allow limited services if a switch to 3G modem has occurred.

Alas 374.33-SDK5 (RT-N66U) still doesn't automatically switch back to ADSL from 3G, so my wan-start script still has to address this ASUS ommission.

As can be seen in the log below, when the switch to 3G occurs, I issue '-j DROP' for the Transmission port 51843 and only reinstate the '-j ACCEPT' when the ADSL WAN connection is restored.

Perhaps you can modify your 'iptables' to futher limit your 3G modem traffic?
