[SOLVED] Router: send packets out all lan interfaces

I am trying to set up a router and the issue that I have run into is that I can either have my wireless lan interface up or my ethernet lan interface up, but not both.  The reason why is because ip route shows them with the same subnet mask:

172.16.17.0/24 dev wllan  proto kernel  scope link  src 172.16.17.1 
172.16.17.0/24 dev enlan  proto kernel  scope link  src 172.16.17.1 
192.168.1.0/24 dev enwan  proto kernel  scope link  src 192.168.1.107  metric 202 

where enwan will be my Wan connection and wllan and enlan are the conflicting interfaces.  Disregard the fact enwan is using a private ip -- its nested within my other router for testing purposes. 

Should I be duplicating packets such that all packets matching 172.16.17.0/24 go out both interfaces or am I looking at this the wrong way? 

Thanks!

Okay, so I think I need to bridge the enlan and wllan interfaces and then use the resulting bridge as my encompassing lan interface..
