60000/tcp This port is open when serial port 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.
60001/tcp This port is open when serial port 2 is
configured for paired-mode server.
As above
60002/tcp This port is open when serial port 3 is
configured for paired-mode server.
As above
60003/tcp This port is open when serial port 4 is
configured for paired-mode server.
As above
68/udp This port is open when the network
mode is DHCP.
This port is used if you configure the device for DHCP mode (as
opposed to Static IP). It is used to communicate with the DHCP server.
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
8899/udp Always open for serial server discovery. This port is used for discovering serial servers. This port is always open
no matter how you configure the device.
Note: The device discovery only works on a local subnet. The port may
not need to be configured in a firewall or NAT.
Other User-specified ports. Other TCP and UDP ports may be open depending on what you specifie
for the device configuration. THESE ARE THE PORTS SPECIFIED IN
THE CONFIGURATION FILE.
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
