RT-LAB : How to Ensure the Windows Firewall or Network Doesn't Block RT-LAB Applications + List of Port / Protocols Used

Network

In order for the simulation to work, a two-way Ping must work:

  • The host computer running RT-LAB must be able to ping an IP address (default is static IP) as displayed by the ifconfig on a Telnet connection to the OPAL-RT target.
  • The OPAL-RT target must be able to ping the IP address displayed by the ipconfig of the host computer running RT-LAB.

Depending on the architecture of your network, it may be possible to accomplish this by configuring routing rules in the gateway between specific IP addresses.

A quick test is to connect a cable directly between the Host PC and the OPAL-RT Target Simulator and try the two-way Ping.
