Easy-IP source NAT on Huawei USG firewall

A short video describing EASY-IP source NAT on Huawei’s USG firewall to assure that our intranet users can acccess the Internet.

The easy-ip is the easiest way to translate private IP addresses on your local area network when you have only one public IP address or the public IP address is assigned dynamically.
