The default base TCP Ports used for accessing serial ports on the console server are:

  • 2000 - Telnet (i.e. 2001 to 2004 on ACM5004)
  • 3000 - SSH
  • 4000 - RAW TCP
  • 5000 - RFC-2217

The Administrator can set alternate bases for these services using the System:Sevices menu (or the Services tab on the System: Firewall menu in firmware pre 3.5). These alternate ranges will then be used in addition to the defaults.

SDTConnector uses the following TCP Ports when forwarding RDP and VNC traffic from the local LAN through to serial ports on the console server :

  • 73XX - RDP over serial from local LAN - where XX is the serial port number (i.e. 7301 to 7348 on CM4148)
  • 79XX -VNC over serial from local LAN - where XX is the serial port number

SDT Connector also uses the standard SSH Port 22 for all tunnelled communications to the console server. The tunnelled traffic is then port-forward to the following LAN Ports:

  • 23 - Telnet
  • 80 - HTTP
  • 3389 - RDP
  • 5900 - VNC
