select, PPTP or L2TP with or without IPSec policy above.
PAP/CHAP/MS-CHAP/MS-CHAPv2 is the most common
selection due to compatibility.
VJ compression - This field is applicable when you select
PPTP or L2TP with or without IPsec policy above. VJ
Compression is used for TCP/IP protocol header compression.
Normally set to On to improve bandwidth utilization.
IKE Authentication Method - This group of fields is
applicable for IPsec Tunnels and L2TP with IPsec Policy.

Pre-Shared Key - Input 1-63 characters as pre-shared
key.

Digital Signature (X.509) - Select one predefined
Profiles set in the VPN and Remote Access >>IPsec
Peer Identity.
Peer ID - Select one of the predefined Profiles set in
VPN and Remote Access >>IPsec Peer Identity.
Local ID – Specify a local ID (Alternative Subject Name
First or Subject Name First) to be used for Dial-in
setting in the LAN-to-LAN Profile setup. This item is
optional and can be used only in IKE aggressive mode.

Local Certificate – Select one of the profiles set in
