Use Aggressive Mode
Selecting the Use Aggressive Mode check box forces the SonicWALL appliance to use
Aggressive Mode to establish the VPN tunnel even if the SonicWALL has a static IP address.
Aggressive Mode requires half of the main mode messages to be exchanged in Phase One
of the SA exchange. Use Aggressive Mode is useful when the SonicWALL is located
behind another NAT device. The check box is only available if IKE using Pre-shared
Secret or IKE using certificates (SonicWALL to SonicWALL) is selected as the IPSec
Keying Mode.
