Cloudflare WARP and Azure Virtual Desktop (Windows365)

emeliyanov · May 10, 2023, 3:10am

Hello! We’ve been using Cloudflare on Azure Virtual Desktops for about a year with no issues. But it appears since WinDivert has been replaced with WinTun, it conflicts with something (possible suspects at the moment are: Crowdstrike Falcon, Azure Guest Agent, Microsoft RDAgent, Microsoft Geneva Agent. Microsoft Defender). That “something” causes routes to bounce first disrupting user connectivity to VM and often ends with wintun crashing. I don’t expect a solution, just posting this in case someone else is googling this and may have any ideas on how to pinpoint the culprit. No other VPN software is installed on the VMs.

This isn’t 100% reproducible. I’m still trying to find a pattern.
This happens in both “exclude” (full tunnel with Azure service endpoints excluded, so only “user” traffic is tunnelled and not RDP) and “include” (three test class A private subnets) modes.
The VMs have Cloudflare resolver (DoH via native Windows 11 support) configured as the default (that is – via ncpa.cpl, outside of WARP)

So far everything is pointing to Microsoft Defender. With Falcon Sensor installed on the system, Defender technically should detect the Falcon presence and switch to passive mode (pizza delivery driver mode, that is – “smell, but don’t touch”). However, it appears that as WARP loads wintun.sys, Defender attempts to insert itself to perform network protection scanning on this newly created network interface. Something was changed in this process in Defender somewhere around April this year, that breaks connectivity. When examining firewall rules, this came up:

This is repeated many times, so there’s definitely a conflict of some sort. I don’t know exactly yet what LpacSenseNdr rule is trying to achieve, but judging by its name it is definitely MS Defender-related (and it’s causing issues for other apps as well). Disabling network protection seems to help, but I’m still investigating. Also, since this is happening somewhere in kernel space, adding warp-svc.exe to the exclusion list has no effect on this.

Spoke too soon unfortunately. Disabling Defender does not help. Even more cryptic stuff now:

Ok, I give up. We are staying on the latest WinDivert version for now.

amerrill · May 18, 2023, 3:03pm

This has been a problem for me as well. Do you know what version is the latest that uses WinDivert?

amerrill · May 18, 2023, 3:40pm

I reverted to Version 2022.12.582.0, which I believe is the latest version to use WinDivert since 2023.3.381.0 mentions the new tunnel architecture. I’m still having major connectivity issues in anything except proxy mode and have been running in Include mode.

I ended up removing WARP from all of my AVD servers after having no luck reverting WARP versions and Windows updates. I’m not seeing any of the DnsProxy timeouts that you’re highlighting in the logs for 2022.12.582.0 but it does look like it’s stuck in a loop of reestablishing the tunnel over and over.

emeliyanov · May 22, 2023, 5:21pm

@amerrill yes you are correct 12.582 is the latest and yes you are correct downgrading doesn’t always help. If a system is impacted, it will remain impacted even after downgrade. And I wasn’t able to reproduce this on my test VMs no matter which WARP version and mode (include/exclude) I use, so if a system is NOT impacted it will remain not impacted. I guess the newer version doesn’t uninstall entirely from the system and leaves some misconfiguration behind.

amerrill · May 22, 2023, 9:02pm

Thank you for the response. I brought up a fresh VM to verify and there is no issue prior to updating. I’ll start digging into the app and see if I can figure out what it’s leaving behind that’s causing issues, even after reverting.
