Installation On An Ethernet Network; Network Setup - Dynamic Ip Address - HMS Netbiter EasyConnect EC150 User Manual

9. Installation on an Ethernet Network

The Netbiter EasyConnect Gateway requires outbound (outgoing) access to the Internet, to be able to
connect to the Netbiter Argos service. When connected on an Ethernet network, it will use the TCP
ports listed below.
Ports for Connection to Netbiter Argos
The Netbiter EasyConnect EC350 will attempt to contact the Netbiter Argos server via port 443.
All other Netbiter EasyConnect Gateways will attempt to contact the Netbiter Argos server via the fol-
lowing outbound ports:
• 5222
• 443
• 80
The above ports are tried in the order shown, and connection attempts will be made to 3 dfferent serv-
ers, with a timeout of 30 seconds for each. This means that it may take up to 4 min 30 sec to establish a
connection (3 ports x 3 servers x 30s).
Other Connection Ports used:
• 502 - Default port if Modbus TCP is used for internal registers
• 502 - Communication with Modbus TCP slave devices.
• 8080 - Extra web server
Important! - To protect against unauthorized access, the use of a network firewall is strongly
recommended. See below.
Note that Netbiter EasyConnect EC220 cannot be installed on an Ethernet network.
Firewall
A firewall is used to control inbound and outbound traffic, thus protecting a network from unauthorized
access. TCPI/IP traffic is targeted at a specific port at the destination IP address, a fact used by a firewall
to allow or block specific kinds of traffic to specific IP addresses. A firewall normally blocks most in-
coming traffic, thus preventing access to the site from the internet, but in some cases the firewall may
also be configured to block outbound traffic.
Netbiter products use the outbound ports listed above to access the servers at Netbiter Argos. At least
one of these ports must be open for outgoing communication to the internet for the Netbiter
EasyConnect product to be able to communicate with Netbiter Argos. Outbound ports are configured
by the firewall's administrator. Please contact your IT administrator if you are uncertain whether out-
bound Internet access is allowed on these ports.

9.1 Network Setup - Dynamic IP Address

When the Netbiter EasyConnect Gateway is using DHCP (the default setting), there is no need to con-
figure any of the IP address related settings. The only changes that may be required are the settings need-
ed to pass a proxy server on the network, see below.
