• Exchange Mode—Choose one of the following options:
- Main—This mode negotiates the tunnel with higher security, but is
slower.
- Aggressive—This mode establishes a faster connection, but with
lowered security.
Note: If either the Local or Remote identifier type is not an IP address, then
negotiation is only possible in Aggressive Mode. If FQDN, User FQDN or DER
ASN1 DN is selected, the router disables Main mode and sets the default to
Aggressive mode.

Association and Key Management Protocol (ISAKMP) identifier for the remote
router:
• Remote WAN (Internet) IP
