Full Tunnel Mode
In full tunnel mode, a virtual connection is created for remote users with private IP addresses
in the same subnet as the local network. This allows them to access network resources in the
same way as if they were part of the internal network.
Figure 268 Network Access Mode: Full Tunnel Mode
SSL Access Policy
An SSL access policy allows the ZyWALL to perform the following tasks:
• limit user access to specific applications or files on the network.
• allow user access to specific networks.
• assign private IP addresses and provide DNS/WINS server information to remote users to
access internal networks.
SSL Access Policy Objects
The SSL access policies reference the following objects. If you update this information, in
response to changes, the ZyWALL automatically propagates the changes through the SSL
policies that use the object(s). When you delete an SSL policy, the objects are not removed.
You cannot delete an object that is referenced by an SSL access policy. To delete the object,
you must first unassociate the object from the SSL access policy.
