characters in the Preshared Key box. Type the same string in the Confirm
Preshared Key box.
The string (which is case-sensitive) must match the string that is config-
ured on the remote endpoints.
8. Configure or disable XAUTH, which is an optional layer of security.
You can configure the TMS zl Module to act either as a client (authenticate
itself) or as a server (authenticate the remote clients). However, config-
uring the module as an XAUTH server is typical. Select one of the follow-
ing:
• TMS acts as XAUTH Client
–For Authentication Type, select Generic or CHAP.
–For Username and Password, you must specify credentials that the
remote endpoints accept.
• TMS acts as XAUTH Server
–For Authentication Type, select Generic or CHAP.
