Topic: how to access a WSUS behind SME

[TeNeCo]

I have the following infrastructure:

WAN<---<ROUTER>---DMZ----<SME>---LAN

One of the PCs in the LAN is a WSUS-Server. How can I access it from the DMZ?

I tried the following:
I added a port forwarding into SME:

TCP Port 8530 to 192.168.2.2 (address of the WSUS)

The Client tries to access the WSUS via the IP-address of the SME:8530

But that isn't working. Has somebody an idea?

It seems you are running WSUS on the custom port as SME Server already uses port 80, so that should be OK. I don't know if opening the TCP port is enough, you might need to open the UDP port as well as I believe a webserver uses both.

Two questions:
1. Did you review the log files from both servers?
2. Are clients in your LAN able to reach the WSUS server?
