i'm trying to figure out how to do static nat for two ISPs when one of them gives us a static block and the other a dynamic ip.
basically i've been made aware of
ip nat inside source static x.x.x.x y.y.y.y route-map isp1
ip nat inside source static x.x.x.x z.z.z.z route-map isp2
but this won't work for me as currently i have to use
ip nat inside source static x.x.x.x int cable-modem0.0/0
since we don't have a static IP for the cable modem service.
is there a way to work around this so i can have it use the cable interface and static nat out there while at the same time having it static nat out the dsl interface for the same services?
(i'm basically trying to accomplish a dual ISP setup and to have fail-over to the dsl line if/when the cable line goes down. i've gotten the dynamic nat stuff working by using route-maps for the dynamic nat translations, and am now trying to get our static entries to fail-over as well, or exist all the time also)
