Port forwarding
Port forwarding allows the user of the LT-4100 system to access IP data running on specific equipment
which is connected to the LT-4100 LAN port
When setting up port forwarding for the LT-4100 system the user needs to establish port forwarding rules.
These user needs to configure the external port, the local IP address, the port, and the chosen protocol.
To ensure smooth operation after setting up a port forwarding rule, the IP address(es) of the user
equipment that shall be reachable remotely should be statically assigned. If the LT-4100 is configured as
DHCP server make sure to assign IP addresses outside the DHCP server range.
An example of a configured port forwarding rule can be seen on Figure 115. There a PC running a web
service on tcp port 8080 is connected to the LT-4100 LAN port. The PC is statically assigned the IP address
192.168.1.202. Adding this port forwarding rule allows access to the Web service.
To verify whether the rule was set up correctly and the web service is accessible remotely visit the URL
https://<public-IP-of-terminal>:8080
IMPORTANT
: TCP port 443 is reserved by the LT-4100 terminal and may not be used as external port in
port forwarding rules and will not be forwarded to any configured DMZ host.
NOTE:
Remember to click ‘Apply’ after adding the rule to the table
