Re: load balance outbound w/ NAT (router)

You need to specify what kind of traffic has to be translated when you are using, ip nat inside source static 10.10.0.3 200.20.7.130 route-map ISP-1

Re: load balance outbound w/ NAT (router)

if you turn on CEF switching then your router should load balance per-destination across the routes you statically specified.

ip route 0.0.0.0 0.0.0.0 s0

ip route 0.0.0.0 0.0.0.0 s1

ip cef

if you want per-packet you can use the interface load-sharing command.
