Westermo ADSL-350 - Manual (Page 24)

24 6623-2231
Start by configuring a DDNS account, and a domain name, for this example the
server.mine.nu name will be used. Once DDNS is configured in the ADSL-350 it is
time to create a firewall rule that allows traffic coming from the Internet to the
ADSL-350 on a specific port to be forwarded to the HMI. For the purpose of this
example the incoming port that the PC will be using is 12345.
Navigate to the top-menu
Firewall followed by the sub-menu Port Forwards and then
click on Add new port forward. In the screenshot below the information above has
been used to create a port forward to the HMI. The user on the laptop would open his
browser and type in the domain name followed by a colon and then the custom port, e.g.
http://server.mine.nu:12345
.
Once Update is clicked the port forward is active. If the HMI has been configured
properly it would now be accessible.
Note! If the connected LAN device, e.g. the HMI or PLC, does not have the possibility
to set a default gateway the use of 1:1 NAT can be used. For more information about
how to achieve this please refer to the Management Guide.
