I just need some clarification on the ports that need to be opened on the client. Following this document, https://docs.microsoft.com/en-us/sccm/core/plan-design/hierarchy/ports#BKMK_CommunicationPorts Client Wake on Lan UDP 9 Wake-up Proxy UDP 25536 Remote Control TCP 2701 Remote Assistance TCP 3389 Are there any additional needed?

Hello everyone, I'm a little bit confused about ports for SCCM client. Our network environment has a restricted vlan. The clients are in the restricted vlan. I don't know which ports are needed for pushing and communicating with our SCCM server. These port would be permitted on our company firewall. Also clients have permitted ports for WMI and file and printer sharing on each PC by GPO. I read the MS Technet documentation of SCCM and I've found these ports: 80 (TCP) 433 (TCP) 1433 (TCP) 445 (TCP) 10123 (TPC) Are these ports ok or some of them are wrong? I want to permit only necessary ports. Thanks for any answer Tom

Attached is a diagram I created to understand the type of communication and porst required open for basic SCCM site communication, client communication, and WSUS/SUP. I gathered this information from Technet articles but need verification that it is correct. For example, is it true that if you have WSUS/SUP installed on all of your site servers that they will need ports 8530/8531 to communicate WSUS information to each other or is that handled via SQL replication? Also if client push was used would RCP be required from the secondary to the client? TechNet shows it is but we have not had that port open and have been successful. Is port 80/443 required for any communication between the CAS, primary and secondary site? The client should not need to talk to the WSUS/SUP at the primary if it is available on the secondary so ports 8530/8531 can be closed between the client and the Primary? Would SMB need to be open between the primary and Client if client push is selected to run from the secondary (is this possible)? Anything else you find missing from or needs to be changed in the document? Thank you for the help.
