Remote Client tab
The Preferences Remote Client tab is used to establish a path (tunnel) to a secure DNS server
to resolve client DNS names (as opposed to using a public DNS server) and to set the remote
client idle time-out period.

Client DNS resolution redirection
By using the Client DNS Resolution Redirection feature, VPNremote Client-initiated DNS name
resolution requests for specific subdomains can be directed to private DNS servers residing on
a network protected by a security gateway. This allows VPNremote Clients to use host names in
place of IP addresses when accessing corporate network resources without exposing corporate
DNS servers and name resolution databases to the public. Thus, a VPNremote Client can use
public DNS servers to resolve public resources and private DNS servers to resolve private
resources.
Note:
Note:
DNS name resolution requests are redirected at the user side by VPNremote
Client. The remote Client must be running a version of VPNremote Client
software which supports Client DNS Resolution Redirection. Check with Avaya
Technologies for version support information.
You can enable Client DNS Resolution Redirection and enter up to three subdomain names
along with the IP address of the DNS server that will resolve DNS requests for the
corresponding subdomain name.
