DNS Configuration Guide in SECUI Bluemax Next Generation Firewall

In any network system, the Domain Name System (DNS) plays a crucial role in connecting users to websites or services by their domain names. Without DNS, accessing the internet would be far less convenient since you’d need to remember numeric IP addresses for every site.

In a Next Generation Firewall (NGFW) such as SECUI Bluemax NGF, configuring DNS isn’t just about enabling domain resolution. It also supports critical functions like logging, system updates, and security features that rely on connections to external domains.

This guide walks you through the process step by step, from accessing the firewall dashboard, adding DNS server IPs, to testing connectivity so you can be confident everything runs smoothly.
