I am used to working with L2TP tunnels on Cisco and Redback systems, and when we're receiving L2TP tunnels from other partner ISP or access providers it is usually desired to configure authorization of L2TP tunnel establishment for every L2TP tunnel peer.
How is this done in RouterOS?
For example, on a Cisco you do something like (quoted from the Cisco documentation on L2TP)
vpdn enable ! vpdn-group 1 accept dialin l2tp virtual-template 1 remote sp_lac local name lns You will also need to configure local username database entries for the LAC and LNS. The entries are used during the tunnel authentication process. The following is an example of these entries: ! username sp_lac password 7 104D000A0618 username lns password 7 01100F175804 !
and provide the correct password (from the username sp_lac password 7 104D000A0618 line) for the L2TP tunnel to be established. Authentication of PPP session coming in via the L2TP tunnel once it is running are not my concern here.
What am I missing here?
