I manage and deploy many VPN systems running on the Cisco ASA 55XX platforms.

I was wondering if there are any tips and tricks including articles that others can share on how to enhance the performance of the VPN tunnels.

Many Thanks,

The security appliance includes a feature that lets a VPN client send IPSec-protected traffic to another VPN user by allowing such traffic in and out of the same interface. Also called "hairpinning", this feature can be thought of as VPN spokes (clients) connecting through a VPN hub (security appliance).

In another application, this feature can redirect incoming VPN traffic back out through the same interface as unencrypted traffic. This would be useful, for example, to a VPN client that does not have split tunneling but needs to both access a VPN and browse the Web.
