[Question] Applications blocked in Simplewall can still access the Internet through VPN
I have allowed my VPN application to access the Internet in Simplewall, and it connects successfully. However, when the VPN is active, other applications that are blocked in Simplewall can still connect to the Internet through the VPN tunnel.
Is there a configuration setting in Simplewall to block Internet access for these applications even when a VPN tunnel is active? Or is this a bug?
Expected behavior: The blocked application should not be able to connect to the Internet, regardless of whether a VPN is active.
Actual behavior: The blocked application can bypass Simplewall restrictions and connect to the Internet through the VPN tunnel.
App version: <3.8.7> Windows version: <Windows 11 24H2>
This isn't called bypass; since you allow VPNs, all traffic passing through the VPN is permitted.
To control an application's access to a VPN tunnel, use the VPN tunnel software and limit (whitelist/blacklist) apps. Simplewall / WAF is not the place to allow an application and then try to restrict that application's internal functionality. Simplewall handles windows firewall.. the VPN software handles its own application "firewall".
