Troubleshooting the TMS zl Module in Routing Mode
Edit the remote access policy to change the authentication method.
To change the policy on IAS, follow these steps:
i. Open IAS from the Administrative Tools.
ii. Expand Remote Access Policies and find the policy intended for
L2TP user authentication.
iii. Right-click the policy and select Properties.
iv. Click Edit Profile.
v. Click the Authentication tab.
vi. Select the correct check box to match the client’s setting.
4. If the RADIUS log messages indicate that the requests were received and
the user authenticated successfully, there might be one of several prob-
lems:
• The problem is most likely that the policy did not provide the attri-
butes that the L2TP client needs. On the L2TP client, you might see a
message indicating that the server did not send an IP address.
This address can be provided by the RADIUS server, by the user
account in AD if you are using AD, or by the TMS zl Module. To verify
that the IP address can be assigned successfully, check the attributes
returned by the RADIUS server and make sure that they exactly match
those in Table 10-16.
To view these attributes for IAS, follow these steps:
i. Open IAS from the Administrative Tools.
ii. Expand Remote Access Policies and find the policy intended for
L2TP user authentication.
iii. Right-click the policy and select Properties.
iv. Click Edit Profile.
v. Click the Advanced tab.
vi. Check the attributes, removing or editing them as necessary to
match those in Table 10-16.
