How do I setup Multi-Path route iptables
 

Here's my scenario:

172.29.0.19 (computer) has two routes to internet
172.29.0.8 (rogers-modem) NAT external IP 99.x.x.x
172.29.0.2 (dsl-modem) NAT external IP 67.x.x.x

I want it so any inbound traffic from dsl goes back out the dsl and same for rogers. I've been searching and playing with many docs with no luck.

Anyone know how I do this? The multiple routes are on the same device br0. (which I think is causing all my havoc)

Take a look at this site, it has an explanation and some information on how to do this with iproute2 (required).
