Firewall (client router or client OS) blocking outgoing VPN?
by bennypr0fane from LinuxQuestions.org on (#5ABMY)
My colleague cannot access our office PiVPN from her home but I can on my laptop from my home.
So by outgoing VPN, I mean the client trying to connect to the VPN server here, and something inbetween is maybe blocking it.
We successfully tested both laptops (both Linux) at the office going online through a mobile hotspot from my phone, and both had access, so I guess client settings on her laptop should be fine, but I was thinking maybe my colleague's router at home could block her outgoing VPN from reaching the Pi at the office, is that possible? If yes, what settings would I need to check on that router?
Both clients are configured using OpenVPN.
I've also seen reports of Windows firewall blocking clients' VPN, so I thought it might be something on my colleague's OS (Lubuntu 18.04) that's blocking it?
