1.4 TCP/UDP Ports

Table 1-1. TCP/UDP ports.

Port

80/tcp

DescriptionComments

This port is used for configuration of the device using a web browser.

This port is always open no matter how you configure the device.

Always open for the Web server. If you want to use this method to configure the device from outside of a firewall, then a firewall must allow incoming connections to this port.

If you want to use this method to configure the device from the outside of a NAT, the NAT must be configured to forward to this port.

This port is open when any serial

771/tcpport is configured for VCOM mode.

This port is used for communications with the VCOM device driver installed on the computer. This port is open only if you configure any serial port for VCOM mode.

If you want to use VCOM from outside of a firewall, then you must allow incoming connections on this port.

If you want to use VCOM from outside of a NAT, then you must forward to this port.

7000/tcp

Always open for serial server

configuration over TCP.

 

This port is used for configuration and firmware upgrade of the device using the serial server manager. This port is always open no matter how you configure the device.

If you want to configure the serial server from outside of a firewall using the serial server manager, then the firewall must be configured to allow incoming connections on 7000/tcp and allow packets addressed to 7000/udp to be received.

NOTE: Configuring over 7000/udp is not supported.

This port is open when serial

60000/tcpport 1 is configured for paired- mode server.

These ports are used to transfer handshake line state and break state in paired mode configuration. These ports are open only if you configure the port for paired-mode server. Note that serial port 1 uses 60000/tcp, serial port 2 uses 60001/tcp, serial port 3 uses 60002/tcp, and serial port 4 uses 60003/tcp. If a port is not configured for paired-mode server, then the corresponding port is not open.

If you want to connect to a paired-mode server from outside of a firewall, then you must allow incoming connections on these ports.

If you want to connect to a paired-mode server from outside of a NAT, then you must forward to these ports.

 

This port is open when serial

 

60001/tcp

port 2 is configured for paired-

mode server. Applies to LES424A

 

 

 

only.

 

 

 

 

 

This port is open when serial

 

60003/tcp

port 4 is configured for paired-

only.

 

 

 

 

 

This port is open when the

This port is used if you configure the device for DHCP mode (as opposed to Static IP). It is used to

68/udp

communicate with the DHCP server.

network mode is DHCP.

 

 

This should only be used inside of a firewall or NAT.

 

 

 

 

 

7000/udp

Always open for serial server

configuration over UDP.

 

These ports are used for configuration and firmware upgrade of the device using the serial server manager. These ports are always open no matter how you configure the device.

If you want to configure the serial server from outside of a firewall using the serial server manager, then the firewall must be configured to allow incoming connections on 7000/tcp and allow packets addressed to 7000/udp to be received

 

 

 

This port is used for discovering serial servers. This port is always open no matter how you configure

discovery.

NOTE: The device discovery only works on a local subnet. The port may not need to be configured

 

 

 

 

 

 

 

 

 

 

 

in a firewall or NAT.

 

 

 

 

 

 

 

 

 

Other TCP and UDP ports may be open, depending on what you specified for the device

 

 

 

 

configuration. THESE ARE THE PORTS SPECIFIED IN THE CONFIGURATION FILE.

 

 

Other

User-specified ports.

If you want to use these other ports from outside of a firewall, then you must allow these ports.

 

 

 

 

 

 

 

 

If you want to use these other ports from outside of a NAT, then you must forward to these ports.
