Hello 🙂
I'm new user with openvpn and I have set my openvpn server (slackware) in bridged mode.
Now I have 4 network interfaces (one real, three virtual) and it works although I dont know why 🙂.
Could you please explain to me purpose of br0,eth0,tap0 interfaces?
Why eth0 doesn't have any ip assigned but br0 does?
Does all the traffic from my local network come to eth0?
Does all the traffic from my vpn network come to br0?
Is all this traffic forwarded to each other?
Why when I set up default gateway, it's set to br0 and not eth0 when eth0 is the one connected to internet?
What does the tap0 interface do and when does it come to play?
Sorry for so many questions, I've read many tutorials past 3 days and after so much information getting little lost with this.
Thank you for your explanation

hello there,
in short
eth0 is your physical interface
tap0 is openvpn's virtual interface
br0 is used to "bridge" eth0 & tap0
assuming you have setup openvpn in bridging mode.
regards,
Michael.
