Firewall and security considerations
5.4.1
Firewalls
The GE DuraStation uses standard Internet HTTP & HTTPS protocols to connect to GE’s dedicated
environment. Some locations may utilize firewalls or similar filtering devices to secure their
environment.
The following table lists IP addresses and ports that must be allowed for the GE DuraStation to
communicate properly. The DNS names are provided as reference and firewall or filtering device
will most likely only use the IP address and TCP port numbers.
If possible it is recommended to open the entire 165.156.12.xx subnet.

5.4.2
Proxy Servers
It is recommended to use a direct Internet connection when possible. If your environment does
not have this capability you may need to use your installation site’s proxy server. You will need to
obtain the proxy server DNS name and TCP port that it operates on. This proxy information will
need to be entered into the GE CONNECT tab of the configuration tool.
Many sites that utilize proxy servers for Internet access also require the use of a login or other
information to gain access to the Internet. For the DuraStation unit to work properly there may
be a requirement for your IT team to exclude the gewattstation.com Internet domain from
requiring authentication.
