Finish and activate the settings by clicking on Update, the DDNS client will now
track the changes of the ADSL interface of the ADSL-350 and update the domain
server.mine.nu should the unit get a new IP address.
Note! Even though any changes usually are updated / replicated quite quickly, there can
be issues, e.g. at the DDNS service provider, that prevents updates, or introduces delays.
For more critical applications a fixed IP address may prove more reliable, or the use of
other methods to guarantee connectivity. Feel free to contact Westermo Support should
you have any questions about this, or refer to the Westermo website.
How can the ADSL-350 be configured from the Internet?
In some scenarios the user might want to configure the ADSL-350 from the Internet,
either by accessing a DDNS name, or using a fixed IP address from a PC on the Internet.
Since the ADSL-350 is cyber secured by a firewall by default, the user must first allow
traffic from the Internet trying to access the web-interface / webserver of the ADSL-350
to pass through.
Westermo strongly recommends any user opening up the firewall to change the default
password of the ADSL-350 before doing so.
To open the ADSL-350 for access to the web-interface from the Internet just navigate to
the top-menu
Firewall followed by the sub-menu Access Control.
