How To - Configure Dynamic DNS in Cyberoam

Applicable to Version: 9.4.0.2 onwards

 DDNS (Dynamic DNS) is a service that maps Internet domain names to dynamic IP addresses. DDNS serves a similar purpose to DNS. Unlike DNS that only works with static IP addresses, DDNS is designed to support dynamic IP addresses.

One needs to configure the dynamic DNS service in Cyberoam when the Cyberoam’s external (WAN) interface is assigned dynamic IP address. 

Cyberoam supports following DDNS providers:

  • DynDNS
  • ZoneEdit
  • EasyDNS
  • OrgDNS
  • DnsPark

This article describes complete procedure to
