Access LAN when at Home with OpenVPN for Android

girkers · Feb 2, 2021, 3:28 AM

I am using OpenVPN for Android that allows me to only select the apps I want to use the tunnel and it works great, the only issue that when I am at home and connected to the LAN the tunnel drops and I cannot use the apps as they no longer work due to the tunnel being down.

I have researched Hairpinning but I could not get it to work and from what I have read that is not the ideal set up anyway.

Could someone suggest how I go about get my apps to work whether I am connected to the LAN or the VPN so that it is seemless, open to other configuration options as well.

Thanks

@girkers
There may be multiple ways to resolve, hairpinning is one of theme.
Set the OpenVPN server to listen on localhost. Add a NAT port forwarding for the OpenVPN packets to localhost and enable NAT reflection in the rule.

But a cannot tell you if the routing goes well if you connect from inside your LAN. This depends on your device.

Thanks for the reply.

I have ended up using OpenVPN Connect an always on VPN and whilst not exactly what I wanted to do, it works for my apps in that it disconnects the VPN when I am home and works fine.

Just some of my apps when I am connected to the VPN act a little strange but that is for another post.

Cheers.
