Avaya 3.7 Manuel D’Utilisation

To configure Client DNS Resolution Redirection for all VPNremote Clients:

●

Enter a subdomain name in the Domain Name field (for example, 
finance.mycompany.com).

●

Enter the IP address of the DNS server that will resolve DNS requests for the 
corresponding subdomain name in the Protected DNS Server field.

●

Repeat this procedure for up to two additional subdomains, then click Apply.

These settings apply to all Clients in all VPNs. Client DNS Resolution Redirection cannot be set 
uniquely for each Client.

For proper operation, a VPN protecting the specified DNS servers must be configured between 
the VPNremote Client and the security gateway. This VPN must contain a Group that includes 
the IP addresses of the DNS servers defined within the Client DNS Resolution Redirection. The 
VPN services of the “DNS server VPN” will be applied to any DNS requests made by the Client 
to the subdomains defined within the Client DNS Resolution Redirection.

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.

You can set the amount of time that a VPNremote Client can be idle before its assigned IP 
address is returned to the Client IP Address Pool. This is useful if you have VPNremote Client 
users that typically use TCP-based applications (e.g. Telnet, FTP, Web traffic) and leave those 
applications idle for long periods of time. 

Units can be seconds or minutes. The maximum idle time is 65,535 minutes.

Send Syslog messages to receiving hosts after VPN session is inactive for XX minutes enables 
you to set the session inactivity time before issuing a Syslog message. The default time is 10 
minutes.
