I have a Cisco ASA 5525-X running 8.6(1)2.
We have utilized all of the IP address space that our ISP initially provided to us. The ISP has assigned an additional non-contiguous block of addresses to us.
The ASA doesn't support secondary addresses on interfaces. What other options do I have?
Break the outside interface into sub-interfaces and trunk with dot1q. How would I handle routing with 2 (or more) external interfaces (which to use as default)?
Set up a second physical outside interface. Again, how to handle routing with 2 (or more external interfaces?
