These steps were tested under IOS 8.2(2).
Prerequisites
- You need two identical Cisco ASA 5510 appliances
- Both appliances must be running the identical IOS version
- You need at least IOS version 7.0. If you want to use IPv6, you need at least IOS version 8.2(2).
- You need an ASA 5510 Security Plus license on both appliances.
- Both appliances must be in the same mode (single|multiple|transparent|routed). This tutorial uses routed mode. (You can tell the mode your appliance is running under issuing the
show firewallcommand in enable mode.)
