I would dearly love some help on this one as it has me well and truely confused and beating up small furry animals in frustration.
ADSL1 (routed subnet)---atm0/0/0-|--fe0/0--192.168.0.1/24----
ADSL2 (static IP)-------atm0/1/0-|--fe0/1--184.108.40.206/28---
FE0/0 needs to accept NAT translation requests coming from the IP 220.127.116.11/28
FE0/1 needs to route (default router) for machines on other IP's in the /28 subnet.
Default route for FE0/1 needs to go out ADSL1
Default route for FE0/0 needs to NAT, load balance and failover both ATM0/0/0 and ATM0/1/0
I need a virtual interface of some sort that will allow me to assign the IP 18.104.22.168/28 to it, and set it as IP NAT OUTSIDE.
I visualise it as follows:
ATM0/0/0 coupled to Dialer0 get assigned the IP 22.214.171.124/32 on the actual Dialer0 interface. The subnet 126.96.36.199/28 is routed via that /32 IP on the Dialer0 interface. 188.8.131.52/28 is the first IP and the gateway IP for the subnet and is assigned to the FE0/1 interface. The FE0/1 interface needs to static route (no NAT) to the Dialer0 interface.
I now need a "virtual" interface with the IP 184.108.40.206/28 which will static route to the FE0/1 interface. This interface needs to be set as IP NAT OUTSIDE so that port forward requests coming in via Dialer0->FE0/1->Virtual are port mapped to FE0/0
ATM0/1/0 coupled to Dialer1 get assigned a static /32 IP and will accept port forward requests directed to the FE0/0 interface only.
FE0/0 needs to NAT to both Dialer1 and the virtual interface with 178/28 for load balancing and failover.
Existing config follows.
