REPLAY PROTECTION
Replay protection allows the freeGuard Blaze 2100 to check the
sequence numbers of the VPN packets, to determine if the packet has
been received or not. If the packet does not fit into a specific number
sequence the packet will dropped. Replay protection will detect and
protect against man-in-the-middle attacks. Replay detection is enabled
by default on all IKE VPN tunnels.
To disable replay protection, use the
set vpn
command with the
no-
replay
option.
set vpn {name_str} gateway {gw_address} no-replay
