X-320M™ User's Manual
Installation and Setup
SNMP Manager IP
When SNMP is used, this field is used to specify the IP address of the SNMP manager. The default
setting for this field is 192.168.1.25.
SNMP Port
When SNMP is used, this field is used to specify the SNMP port that X-320M™ listens on. The
default setting for this field is 161.
SNMP Trap Port
When SNMP is used, this field is used to specify the SNMP Trap port of the SNMP manager. The
default setting for this field is 162.
IP Filter Range 1 and IP Filter Range 2
For additional security, X-320M™ has a simple built-in firewall. If desired, X-320M™ can be
configured to only allow access to client devices (computers, servers, other ControlByWeb™
devices, etc) with certain IP addresses. Two IP address ranges are provided and only client devices
with addresses that fall within those two ranges will be allowed access. Devices with IP addresses
that fall outside of those ranges will not receive any response from X-320M™. The following are
examples.
To allow access from any device (this is the default setting):
IP Filter Range 1:
0.0.0.0
255.255.255.255
IP Filter Range 2:
0.0.0.0
0.0.0.0
To limit access to only one device (address 192.168.1.33):
IP Filter Range 1:
192.168.1.33
192.168.1.33
IP Filter Range 2:
0.0.0.0
0.0.0.0
To limit access to only devices on the local network and one device on the internet (address
10.143.100.32):
IP Filter Range 1:
192.168.1.0
192.168.1.255
IP Filter Range 2:
10.143.100.32
10.143.100.32
Note: The address specified for the Remote Services server (if applicable) is automatically allowed
through the firewall no matter how the filter is set.
Remote Services
Remote Services initiates an outgoing connection to a server at a remote location. This can be used in
an environment where a web server on the Internet provides a custom web page to X-320M™ and other
ControlByWeb products. Users access X-320M™ through the web server rather than communicating
directly with it. This method is sometimes referred to as “web services” and allows programmers to
create powerful, custom web pages to control multiple devices using the web programming languages of
their choice.
Remote Services initiates the connection to the external web server (rather than the web server initiating
communications to X-320M™). This has two main benefits. First, the web server does not need to know
the IP address of X-320M™. This means that X-320M™ can get its IP address dynamically from a
DHCP server, simplifying the installation. Second, since the connection from X-320M™ is outgoing,
rather than incoming, the local router on the network where X-320M™ resides doesn't need to be
