Can users access the internet after an L2TP tunnel is established
Yes. Only the traffic from users to intranet servers is transmitted by L2TP tunnels. Therefore, tunnels do not affect user access to the Internet.

Can L2TP tunnels be established if the public address of the LNS is not fixed
Yes. You need to associate the public IP address of the LNS with a domain name and set the domain name as the server address on the LAC.
