Required IP ports
As the AK-SM uses IP networking standards to create remote
access it may be necessary to configure any site routers to allow
incoming connections, either from a LAN or WAN view. The figure
below shows a simple IP connection with the AK-SM connected to
a standard network router with a typical factory IP address range.
From within the LAN any remote connections should 'point' to
the master IP address of the AK-SM, in this example
http://192.168.1.100. If however the remote connection is on a
WAN then the LAN router may need to be configured to allow this
inbound connection, with the addition of the web port added tot
he end of the http sting.
Please refer to the port allocation table below for remote IP
connections
Master IP 192.168.1.100
Default Gateway 192.168.1.1
Network Mask 255.255.255.0

Notes for FTP port forwarding in AK-SM units
In AK-SM units, FTP service is a convenient way to download/
upload files and updating database/code. Open FTP server
ports to the public internet is not considered as a safe network
practice. To avoid these issues, Danfoss strongly suggests FTP
functionality in LAN network only . This would reduce the risk
of open FTP ports and enhance network security. However, to
make the FTP work on WAN side, it must have configured FTP
server port opened and forwarded to the public internet.

Lit. no.
1. The port number is required to be typed
into the URL address ONLY if the web port is
NOT configured as 80. For example, if the port
number is configured as 8080, then Computer
A needs to type in http://192.168.1.100:8080,
while Computer B needs to type in
http://172.68.6.108:8080 to access the website
of the unit.
2. If the port number is defined as default
number 80, then it is not necessary to type in
":80" in the URL address, this is because the
HTTP protocol uses 80 as default port. If the
router port forwarding is correctly configured,
it is not required in WAN access either.
