when the Chassis and TestCenter Client are in different VLANs / there is a firewall in between: what TCP/UDP need to be opened in the firewall?
There is a FAQ/KB on this: https://support.spirent.com/SpirentCSC/SC_knowledgeView?id=FAQ10405
However, after following this, I still observe issues. That is, I can reserve only the first port of the chassis. When trying to reserve other/multiple ports, this is not working.
In this non-working case, the firewall blocks several accesses from the Client to the chassis using TCP destination ports 5xxxx (e.g. 51232, 57432, …). Clearly these are not allowed in the firewall, as the KB article did not mention these under "Ingress TCP port ranges" for the chassis (or as egress for the client). Or I am misunderstanding the KB.
When only reserving the first port of the chassis, the client will use TCP destination port 51204, which is listed in the KB. And hence allowed in the firewall and this case is working.
So, what port ranges, in addition to what is mentioned in the FAQ/KB, do I need to open in the firewall?
