Core Issue
The inside global address must be advertised into the routing protocol for remote subnets to communicate with Network Address Translated (NATed) hosts.
Resolution
To resolve this issue, choose one of these options:
- Configure the loopback interface with the same address as the Network Address Translation (NAT) address and redistribute the loopback interface into the routing protocol.
- Configure the static route for the NAT address to null 0 and redistribute the static route into the routing protocol.
For more information and sample configuration on redistribution, refer to Redistributing Routing Protocols.
