This kind of traffic pattern is called hairpinning or u-turn traffic. In the first hairpin example I explained how traffic from remote VPN users was dropped when you are not using split horizon, this time we will look at another scenario. Configuring the Crypto MAP and Extended ACL to allows IPSec traffic on Cisco ASA. This is the final step of our configuration. Here, we need to define an Extended ACL to allow the traffic. Also, here we need to configure the Crypto MAP and call the configured crypto map to the External Interface.

Solution 3: Configure the inside interface for management access. I actually saved the best for the last.
