    Can I get traffic from different policy-classes to NAT out different interfaces?

      Hi,

       

      Using a netvanta 3458 I've got a setup roughly like the WAN link failover app note on this site where I've got two WAN uplinks on eth 0/1 and 0/2, traffic coming in from the LAN on various VLANs via the switch ports.  The wrinkle I'm trying to add to that scheme is to have the traffic from our GUEST VLAN prefer the opposite WAN link.  i.e. When both uplinks are up, guest traffic routes out the secondary by default and fails overt to the primary.

       

      I've tried to do this with PBR and with VRFs but it seems that at the end of the day the administrative cost of the default routes trump everything and I can only ever nat traffic out the winning route's interface.

       

      What am I missing?

       

      Thanks for you insights!
