There are several prerequisites for configuring Avaya Aura® Web Gateway network settings. These prerequisites are not required if you only need to update the DNS or NTP server IP addresses.
If you plan to change the IP address or FQDN of an Avaya Aura® Web Gateway node, add a new element for this node on System Manager on the page.
If you plan to change IP addresses or FQDNs of Avaya Aura® Web Gateway nodes and you do not use DNS servers in your deployment, add host names of all Avaya Aura® Web Gateway nodes to the /etc/hosts/ file on System Manager.
If you plan to change IP addresses or FQDNs of Avaya Aura® Web Gateway nodes and you use third-party CA identity certificates, obtain new certificates with appropriate FQDNs from your CA.
If you plan to change the IP address of an Avaya Aura® Web Gateway node, ensure that the new IP addresses are available in the appropriate subnet.
If you plan to change the IP address of an Avaya Aura® Web Gateway node, ensure that the network adapter or virtual switch of the Avaya Aura® Web Gateway virtual machine is configured with the appropriate subnet for this IP address.
