DNS
The Dynamic DNS protocol associate a DNS name to an IP address of the same Host, even if the last
change through time.
Below you find the main commands.
To configure the username to be used for the DDNS Server authentication, use:
set ddns username <username>
To set the authentication password:
set ddns password <password>
To configure the Dynamic DNS server:
set ddns system <ddns-server>
where <ddns-server> can be:
To set the DNS name associated with host:
set ddns alias <dns-name>
To configure the update period of the DNS:
set ddns update-period <value>
In order for the mechanism to work properly on the router, you have to set a DNS address that
allows to find the IP address associated to the system in use. To do that, use:
set dns <dns-server>
Below you see a complete example:
set dns 8.8.8.8
set ddns username [email protected]
set ddns password not-so-secret123
set ddns system [email protected]
set ddns alias [email protected]
set ddns update-period 3600
set ddns on
where
<remote-ipaddr>
is the IP address of the remote log server.
