I have gotten my VPN connection to work. However, I am not able to ping or otherwise access systems connected to the Mikrotik's ethernet ports.
I think it's because the l2tp-in1 interface is not part of the LAN list nor connected to the default bridge. I'm not sure how to make that connection.
Based on topic 161454, the "/ppp profile set default-encryption set interface-list=LAN" command was used to make the VPN profile part of the LAN list. However, there was only 1 VPN client. In my case, there maybe a couple of simultaneous connections, and a pool of addresses has been created for the VPN clients. If the "/ppp profile set default-encryption set interface-list=LAN" is not correct, how do I resolve my issue?
Thanks!
My configuration.
