Multiple tun loadbalancing question

[Leonardo Santagostini]

Hello all,

I have one freebsd 8.1 box with 3 3G mobile broadband connection.

All connections works fine, but i want to do loadbalancing / fault tolerant
with this 3 connections.

I was reading about lagg interfaces, but i think is not the proper
direction.

Someone can point me to the rigth one?

Thank you very much.
