Hi,
Is it possible to specify a port range for the comms from the DMA to Cube? e.g. restrict it so it can only use ports in the range 10000-20000?
To make our Infosec guys happy, they’d want a limited port range instead of having it wide open, as we have some instances of Cube that are not in the same VLAN as the DMA.
Thanks
Chris
Hi Chris,
There is a similar question in Dojo about this topic:
.NET Remoting with eventing port
It’s not possible to specify the port range to be used for eventing.
This is a limitation of the .net framework.
As indicated by Wale, a possible workaround could be using polling instead of eventing.
When the communication between the client (Cube) and the server (DMA) is via .Net Remoting (Eventing) the DMA will open a random port on the client. This port will be in the port range for TCP/IP defined by the OS.
If the communication is via .Net Remoting (Polling) the client establishes a fixed port connection to the DMA and all communication goes via this port. Your firewall in this case can then be confgured to allow traffic only on this port.
You can find in the help pages more details on Eventing vs polling. Also configuring client communications.
