I googled to find what I need but I couldn't find the exact article that I am looking for.
This is my scenario.
I already have a WSUS 3.0 & sp2 running using port 80 on windows 2008 R2 in the network.
The thing is that I have many remote users who need to update MS updates no matter where they are.
So I decided to set up the downstream server in DMZ using DNS so if they are inside, they cannect to the wsus server inside and if not, they can connect to the wsus server in DMZ.
My questions is that can I use the default port 80 for the downstream server? any security issues? What if I want to change the port 80 on the upstream server to 8530?
Can I still do that? does it affect to the current clients? If so, how?
Once I change it, the remote users will be OK? How can I configure for the remote users to download updates from MS even though they get approved from a downstream server?
All I want is to have all computers update from either wsus once I approve.
Thanks in advance.
