I have a PC running Windows 10 Pro 1909 and MWB Premium 4.1.0.56 Update Package Version 1.0.23404 and Component package version 1.0.889

I have a VPN Server App installed on the PC and have a port forward rule in my router to forward incoming requests on port 443 to my PC. Of course this opens up all sorts of attempts to get into the system but since the clients that are validly connecting come from a small number of know IP addresses I have modified the firewall rule on the PC to only pass through requests from specific IP addresses and to drop all others. This works and stops my vpn server log from filling up with invalid connection requests.

This has been working as expected but since 4/42020 I have started to see blocked website entries in MWB all Inbound for my vpn server app. The fact that MWB stops these is great but I would have thought they would have been blocked already. 

I'm assuming that the Real Time Protection module that is catching these Inbound requests is inserted in the network stack prior to the Windows firewall. Can you confirm that for me, otherwise something is not working in the firewall rules.

Even though I've been running MWB on this system for quite a while, it is only since 4/4 (round about the time Component Update 1.0.867 was rolled out) that I have seen these messages in MWB so something certainly improved. Good work.

Thanks

Mike

The Premium license key is backed up and reinstated. All user configurations and other data are removed. This process requires a reboot.

Greetings,

The Web Protection module in Malwarebytes works through the same WFP APIs as the Windows Firewall itself which means that, at least as I understand it, they are actually both on the *same* level within the network stack.  This indicates that perhaps connections are getting through that should not be somewhere up the line if I understand your setup correctly.

Thanks for the response. I guess that even though they are using the same API Web Protection is actually checking the requests prior to the Firewall itself. 

No unwanted connection requests are getting through to the VPN server which is the behaviour I want.

MWB stops known malicious sites from geting through and the firewall stops any others which aren't flagged as malicious. So all is good.

Mike
