ports to open in firewall windows 2008

we have zcm11 running on a windows 2008 server.

we have tcp/udp port open for
13331, 4011, 1761, 997, 69, 67,9971, 8009, 8005, 7628, 5950, 5750, 5550
but still are unable to pxe boot.

Only after turning off windows firewall for domain network location does it work.

What other ports are needed for pxe to function?

Dmilam,

PXE uses a random port...

Re: ports to open in firewall windows 2008

Dmilam,

AFAIK no, it's any port

Hi Shaun

Is that specific to Zenworks? I Thought pxe was using from 67-69 and 4011? Or is that only the pxe request from a client?

Nop1983,

it's the request - the session is set up on a random port

Okay, so it's the PXE/TFTP transfer that is running on a random port, right? Is this unique to ZENworks PXE?

So it's not a good idea or even possible to activate the firewall on a server hosting the PXE/TFTP content? 😉

Re: ports to open in firewall windows 2008

Great, all I needed to know. I need a good reason not to enable the firewall on the ZENworks server(s), and this is fine. Thanks 🙂

But, is it only PXE in ZENworks that used random ports? ie the MS WDS uses 67, 69 and 4011, as I can se it's bound to that.

Nop1983,

I /thought/ it was all of them, but I may be wrong...
