Hello , Dear developers, I was looking at the openl2tp docs, I would like to know if is it possible to build a L2 tunnel over the internet to form a point (server) to multi point clients architecture.
The clients should build the tunnel to the server to provide ethernet Lan connectivity to the hosts conneced behind in a transparent way (acting as a bridge domain)

All the examples I've seen shows how to set ppp interfaces.
Is it mandatory to set an ppp interface for the tunnel? I just want to pass ip traffic within the tunnel.

So, Is there any quick implementation example between lets say two
clientes and a server?
My final goal is to deploy a LNS server in my centos with 200 tunnels with 50 host behind each tunnel. Those host behind the tunneles should not be able to connect between them.
Is that possible ?
Thanks ;

btw; I achieve this using GRE writting a few lines:

ip tunnel add netb mode gre remote local ttl 255
ip link set netb up
ip addr add dev netb
ip route add dev netb

ip tunnel add neta mode gre remote local ttl 255
ip link set neta up
ip addr add dev neta
ip route add dev neta

It is not good for me since I need to define static routes.
Any advice would be wellcome;
