Cannot access LAN through VPN with local bridge
You can’t access the IP address of the ethernet card that is bridged to your internal network through the VPN connection. It’s a Linux-specific limitation. you can do it with a windows-based machine. A simple solution is to “SSH or telnet to your local router, or any SSH-capable machine” and then from there “SSH or telnet back to the SE server”.
