I currently have two external IP addresses (cable & DSL), buth dynamic with dyndns setup to provide names. Using the default setup, I am currently routing everything out the cable using NAT.
I would like to be able to route SIP traffic out the DSL link (all SIP traffic should come from a single host in our LAN). Are there other special considerations for SIP traffic with the SIP helper? (which seams to be working pretty well in the single cable modem setup).
I would like to route all other traffic out the cable WAN.
If either is down, would like to failover to the other.
Is this possible? I have tried several attempts at multipath setup but I can't get it right.
Thanks!
