3G Multiwan no OpenWRT

Lately, OpenWRT become an alternative firmware for the router. With a GNU/linux based system, OpenWRT is built from the ground up to be a full-featured, easily modifiable operating system for the router. You can have all the features you need with none of the Bloat, powered by a Linux kernel that's more than most other recent distributions.
