What if users inside your office need to access an internal server using its public IP or public domain name?

๐Ÿ‘‰ Thatโ€™s where U-Turn NAT (Hairpin NAT) comes in.

The traffic goes out toward the firewallโ€™s public interface and is translated back toward an internal server.

IPSec uses ESP (IP Protocol 50) to carry encrypted VPN traffic.

But NAT devices can create problems because ESP doesn't use TCP or UDP ports.

NAT-T solves this problem by encapsulating the IPSec traffic inside UDP.
