Configuring NAT hairpin
Configure NAT hairpin on the interface connected to the internal network. NAT hairpin supports P2P
mode and C/S mode.
• To configure the P2P mode, you must configure outbound PAT on the interface connected to the
external network and enable the EIM mapping mode. Internal hosts first register their public
addresses to an external server. Then, the hosts communicate with each other by using the
registered IP addresses.
