Table C-5. Differences between VPN tunnel types
Operation Gateway-to-Gateway VPN Tunnels Client-to-Gateway VPN Tunnels
Exchange Mode Main Mode—The IP addresses of both
gateways are known (especially when
FQDN is used), so each gateway can
use the Internet source of the traffic for
validation purposes.
Aggressive Mode—The IP address of
the client is not known in advance, so the
gateway is programmed to accept valid
traffic sourced from any Internet location
(i.e., less secure).
Direction/Type Both Directions—Either end of the VPN
tunnel may initiate traffic (usually).
Remote Access—The client end of the
VPN tunnel must initiate traffic because
its IP address is not know in advance,
which prevents the gateway end of the
VPN tunnel from initiating traffic.
