4.3 How to Define Local Service Ports
The TPR utilizes TCP ports for the data transfer in the network. TCP
ports are address components that are characterized by their port
number. Ports are used to establish connections and to assign data
packets to the correct services.
Certain services (HTTP, HTTPS, SNMP, etc.) have permanently
assigned ports.
You can specify port numbers for the following local services:
• HTTP (Default = 80)
• HTTPS (Default = 443)
• SNMP (Default = 161)
• ThinPrint (Default = 4000)
TCP ports that are configured as local service ports cannot be used
for the communication with the printer. Assign free port numbers to
the local service ports in order to use the default TCP ports for the
communication with the printer.
Example
If you assign the port number 8080 to HTTP, the printer homepage is
displayed when entering the IP address of the TPR into the browser.
To open the TPR Control Center, add the port number to the IP
Masquerading Enables/disables masquerading.
Masquerading is a type of NAT (Network Address
Translation). In NAT, all external IP addresses are
translated to the local IP address.
ICMP Enables/disables the routing of ICMP packets to the
printer IP address.
In IP networks, ICMP is used to transmit error messages
and queries, for example 'ping'. If the option is enabled,
queries will be answered by the printer and not by the
TPR.
