Connections blocked while using ExpressVPN #383

ugahm commented 5 years ago

Since March update many of my applications are blocked while connected to expressvpn on Windows 7. I can not connect to the gateway of my router while VPN is connected

Some examples in the dropped packet log:

Blocks access to gateway for router portal: "‎4/‎12/‎2019 ‏‎7:34:16 PM","xxxxxxxxxxxx","xxxxxxxxxxxxxxxxxxxxxxxxx\chrome.exe",192.168.1.1:443 (Remote),192.168.xxx.xxx:7398 (Local),TCP,"Provider\ExpressVPN WFP Tool - block all ipv4 outbound filter",#3802321,IN,BLOCK

That is what ExpressVPN itself blocks. Just like Windscribe, it adds a new sublayer to the Windows Filtering Platform (which is what simplewall does, too). It should block other gateways, such as your router, otherwise you'll get leaks outside the VPN tunnel. As you can see in simplewall's log, the origin of the rule blocking these connections is Provider\ExpressVPN WFP Tool - block all ipv4 outbound filter, not simplewall.

If you mean that you can't access any other computers on your local network anymore, then ExpressVPN should include the option to allow local network traffic.
