On April, 5th Wyse published a new Wyse P20 Firmware Release Notes document for their Zero Client device. Amongst the new features announced there are some important PCoIP port changes.
- Changed the UDP port number used for data plane communications from 50002 to the IANA reserved port for PCoIP traffic (4172).
- Changed the TCP port number used for control plane communications from 50002 to the IANA reserved port for PCoIP traffic (4172). This affects connections that are not brokered by a VMware View Connection Server.
Teradici has registered port 4172 with IANA (Internet Assigned Numbers Authority) and this is going to be the official PCoIP port moving forward. IANA is responsible for maintaining many of the codes and numbers contained in a variety of Internet protocols. They provide this service in coordination with the Internet Engineering Task Force (IETF).
Not much has been published but I managed to find the Release Notes for Wyse P20 mentioning these changes. To download document click here.
So, from 50002 to 4172 (both TCP/UDP).
I would expect all PCoIP enabled devices to have firmware update released soon to reflect those changes. These changes are a great step towards ratification of the protocol as a standard internet protocol.
