Introduction
In some applications you may have a restricted network that uses some type of firewall. With a tightly secured firewall enabled you will not be able to access your BlueHeat/Net. To allow access to the BlueHeat/Net through your firewall you will need to permit some specific TCP UDP ports that BlueHeat/Net unit uses through. A list of all of the TCP UDP ports that BlueHeat/Net will use is listed below.
Master List of TCP and UDP Ports Used by the BlueHeat/Net
Notes:
- This list is based off the default settings for the BlueHeat/Net net. You will notice the the BlueHeat/Net specific TCP ports start from a base range of 49152. You can also change this base value to by one the BlueHeat/Net configuration mangers using (WCM, TCM or SCM) and then all of the BlueHeat/Net specific TCP will then be referenced starting from the value you specify.
- This list does not include any port that you may setup using the BHN Raw Socket personalities. If you are using Raw Socket you should also make sure to include those ports list of allowed ports during your firewall setup.
- The list below shows the maximum number of ports need (from a 16-port BHN unit), your device may only have 2,4, or 8 ports, so you will only need to allow for that range of ports only.
| Port | Description |
|---|---|
| 20 TCP | FTP – data port |
