Quick Assist MS problem
Hi everyone, I have a big problem: microsoft's quick assistance app no longer works across my entire network. Are there any known problems with the latest fw installed? I also tried to open all vs all but it still doesn't connect to any PC. But sometimes it connects, for no reason. PC All the same (clones), before the last FW it worked without particular problems. Thanks

In general, unless you're spanning multiple subnets/networks, the firewall won't be able to block traffic from PC to PC on the same network since that traffic doesn't traverse the firewall in order to get from the source to the destination.
If the firewall is denying this traffic, there should be a deny log in traffic monitor that lines up with that traffic. Quick assist works over port 443 and attempts to access https://remoteassistance.support.services.microsoft.com, which is exempted from the HTTPS proxy by default.
