Virtual Private Networks
Configure an L2TP over IPsec VPN
4. For L2TP Server IP Address, type the IP address that the TMS zl Module will
use on L2TP connections.
This IP address cannot be on a subnet that is already configured on the
TMS zl Module. It must be a virtual IP address in the same subnet as the
virtual IP addresses that will be assigned to L2TP users.
5. Click Apply My Changes.
6. Click Save.
The domain names of RADIUS servers configured on the module are listed in
the RADIUS Domain field of the table below. L2TP users must be within one of
these domains in order to be authenticated. For example, if the domain is
company.com, user1 must authenticate as [e-mail].
However, if you did not configure a domain name for a RADIUS server when
you added it earlier, the domain is listed as global in the RADIUS Domain field.
All users without a specific domain name or with a domain name that is not
specified for another server will be authenticated to the global server.
