Require Authentication of VPN Clients via XAUTH - 
So that all the users connecting to he corporate network 
are authenticated. Unauthenticated traffic will not be allowed

Management via this SA: - Optionally, if you want the Remote 
users to manage the  SonicWall security appliance, 
select the management method, either HTTP or HTTPS.

NOTE: You will need to separately add the DHCP server using the +ADD button

Relay IP Address (Optional):-
If set, this is used as the DHCP Relay Agent IP address (giaddr) in place of this SonicWall's LAN IP address. This address is only used when no Relay IP Address has been set on the Remote Gateway, and must be reserved in the DHCP scope on the DHCP server.
