Code:
Router Model         Asus WL-520GU/GC
Firmware Version     DD-WRT v24-sp2 (06/09/09) mini-usb - build 12268M NEWD Eko
I don't know as if the hardware would make a difference, but what brand and model router are you running?
I am using the same router you are, Asus WL-520gU (I haven't put mini-usb on it since I haven't had a need to use the USB port).

Regarding the DD-WRT security hole, if you don't want to upgrade just yet for some reason, it can also be addressed with a firewall rule, as seen on the DD-WRT homepage.

Thanks to those who have weighed in on this. I am leaning towards re-enabling the firewall and forwarding the necessary ports, but will have to do some testing for that.
