System Center Virtual Machine Manager Network Communications Ports (UDP/TCP)
Securing your data center typically includes restricting network traffic ports to only those ports that are required, especially traffic to and from your back end monitoring, deployment and management toolsets. This includes limiting the types of traffic to your System Center Virtual Machine Manager deployments. The list below includes the ports used for Virtual Machine Manager – but is not all inclusive of other ports that may be necessary for domain or host to host communications.
Also – keep in mind that publishing VMRC through a reverse NAT, ISA or TMG gateway can be tricky since the client will attempt to resolve back to the Hyper-V host. This will need to be taken into consideration if clients require VMRC access.
