Bypass proxy for local IPs #71

Closed s0bm9928 closed 2 years ago

s0bm9928 commented 3 years ago

WPP seems to use the proxy server for all HTTP connections - even for the local WSUS server. Can an option be added to list IPs and/or URLs that bypass the proxy, similar to how a web browser is configured?

WPP uses the proxy only to download or upload things from the Internet, not to communicate with WSUS. Can you be more precise on what connections go through the proxy?

s0bm9928 commented 2 years ago

When publishing a package from WPP to WSUS I see a lot of http traffic hitting the proxy destined for WSUS. I thought WPP uses a direct SQL connection to the WSUS database and not http. But from the proxy logs it looks like a lot of http.

That’s weird. All connections use the SDK, which doesn’t account for the proxy. Do you have declared a proxy in IE settings at System level?

s0bm9928 commented 2 years ago

No

DCourtel commented 2 years ago

WPP is installed on a remote computer or directly on the WSUS server?

s0bm9928 commented 2 years ago

On the WSUS server.

What happens if you remove the proxy from WPP settings?

s0bm9928 commented 2 years ago

Then I don't see http traffic hitting the proxy bound for WSUS. But then I obviously can't download Adobe updates.

WPP uses the proxy only to download binaries from the Internet when publishing updates from a catalog. Can you try to make a network capture with Wireshark or another tool and send me that over?
