Configuring NAT with DNS mapping
NAT with DNS mapping must operate together with NAT Server and NAT with ALG.
To configure NAT with DNS mapping:

2. Configure a DNS
mapping for NAT.

By default, no DNS mapping for NAT
exists.
You can configure multiple DNS
mappings for NAT.
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.
• In C/S mode, the destination IP address of the packet going to the internal server is translated
by matching the NAT Server configuration. The source IP address is translated by matching the
outbound dynamic or static NAT entries.
NAT hairpin typically operates with NAT Server, outbound dynamic NAT, or outbound static NAT.
They must be configured on interfaces of the same interface card. Otherwise, NAT hairpin cannot
function correctly.
To configure NAT hairpin:
