How do I change a domain name on my Mirapoint or RazorGate appliance?

Solution

Domain names can be changed using either the CLI, or Administration Suite Setup Wizard.

Domain names are changed in the DNS records that refer to IP addresses on the Mirapoint or RazorGate appliance.

For every IP address associated with a network interface, there must be a DNS PTR record for that IP address referring to exactly one domain name. There must also be a DNS A record for this domain name that refers to that IP address and only that IP address. In other words, there must be a one-to-one correspondence between A and PTR records, and the records must agree.

For all domain name changes, the SSL certificates must also be regenerated.

Changing a Domain Name for an Alias IP Address

In Release 2.7 and later, to change the domain name in the A record that refers to an IP address alias, use the CLI Ssl Newcert command to regenerate the SSL certificate associated with the IP address alias. For example:

Ssl Newcert IP-address

Where IP-address is the IP address or fully qualified domain name associated with the network interface.

In releases prior to 2.7, to change the domain name in the A record that refers to an IP address alias, do the following:

1. Delete the IP alias from the network interface (port number on the NIC). Use the following command:

Netif Deletealias portnum IP-address

Where:

• portnum identifies the Ethernet port, as labeled on the system back panel. The possible values are port0, port1, and port2. This port must currently be bound.
• IP-address is the IP address alias you want to delete from the port.

2. Add the IP alias to the network interface again. Use the following command:

Netif Addalias portnum IP-address

This regenerates the SSL certificate.

Changing a Domain Name for a Primary IP Address

In Release 2.7 and later, if you want to change the domain name that refers to the primary IP address of an interface, use the CLI Ssl Newcert command to regenerate the SSL certificate associated with the primary IP address. For example:

Ssl Newcert IP-address

where IP-address is the IP address or fully qualified domain name associated with the network interface.

In releases prior to 2.7, if you want to change the domain name that refers to the primary IP address of an interface, do the following:

1. Delete all IP aliases for the interface as described above.
2. Use the Netif Unbind command to unbind the primary IP address of the interface.
3. Use Netif Bind to rebind the interface to the IP address.
4. Add your IP aliases to the interface again.
