Mulithomed 1800 Router

[rcrobert]

Router has two interfaces connected to the internet. F0/0 to cable modem, F0/1 to T-1 line and F0/0/0 is LAN interface. I am using dynamic NAT/PAT for LAN access to the internet and I static ports forwarding for external access to servers on the LAN.

Is OSPF the best routing protocol to use for failover and load balancing? Do I need to use Route-Maps with NAT for supporting both interfaces? Does anyone have a sample config of a mulithomed router using dynamic NAT on both interfaces? Thank you.

Thanks for the info. What about for dynamic NAT? Also, should I use OSPF to route traffic out of both interfaces to the internet? If so what are the OSPF statements to route traffic out both interfaces to the internet? Thank you!!
