SCCM source ports

Hi,

does anyone know what source ports an SCCM server uses to communicate with clients? I know that destination ports are 80, 135, 443 and 445. What ports I'd need to specify as destination ports in order to create firewall rules?

Regards

The Microsoft Ports for SCCM diagram is here

http://technet.microsoft.com/en-us/library/bb632618.aspx


It will show you what SCCM feature between what SCCM service uses what port...

Cheers for that MarkieS. I know that diagram and the article. although I'm not sure what ports I should specify on a firewall as source/destination ports. From what the article says I understand that ports mentioned in paragraphs: 6, 7,8, 11, 13, 15, 16, 17, 18, 19 should be configured as the source ports on the client side firewall to allow client --> server communication and there is no server --> client traffic specific ports. Is my thiinking correct?

What firewall are you looking at.  A local client firewall?  Windows Firewall?

SCCM Client sends using the ports listed.  Windows firewall doesnt block outbound traffic.

server --> client traffic ....  Any information sent to the SCCM client would be as an RPC to get it to do something and send some information back.  

Gotta head off now - back on tomorrow!

cheers

MarkieS comment is right kilaa, you have to tell us what kind of firewall are you going to use and for which direction e.g. server to client? client to server? both?
Are you looking to use this for clients over the internet for the IBCM mode?

I'm looking at a local client firewall. I'd like to know what ports would need to be opened for the inbound and outbound traffic.

You will need

Server -> Local client - RPC (135)
Local Client -> Server - Ports as listed above diagram.

If you are using Windows Firewall you should only need to check RPC is allowed incoming as Windows Firewall doesnt block anything Client -> Server.
