Learn to set up network connections for the RTDS Simulator in three ways: stand-alone local area network (LAN) setup, main network setup, or remote access. At the end of this blog post, you’ll find the TCP and UDP ports information related to RTDS.

TCP Ports Used By RSCAD:
4068,4069,4070,4071 (Required To Download/Run Cases)
TCP Ports Used By Local Computer:
23 (To Telnet to a rack, or other hardware)
There are also various TCP ports that are user controlled, such as:
502 (If Using Modbus Script Functionality on the Default Port)
— (Any Port Specified in the Listen on Port Runtime Script Command)
— (Any Port Specified by the PMU Component in Draft)
2,4455,4456,53693 (Required To Download/Run Cases)
The *SOURCE* TCP and UDP port numbers are randomly allocated by your PC (this is typical of most TCP/IP client software).
However, there are times when RTDS racks need to send asynchronous commands back to the RSCAD clients which can cause issues when the traffic goes through a NAT firewall. For this reason using a NAT firewall between RSCAD clients and the RTDS racks is not recommended. Using simple TCP/IP routing between RSCAD clients and RTDS racks works fine
