LOG MESSAGE
DESCRIPTION
!! WAN IP changed to 
If the ZyWALL’s WAN IP changes, all configured “My IP Addr” are 
changed to b “0.0.0.0”. If this field is configured as 0.0.0.0, then the 
ZyWALL will use the current ZyWALL WAN IP address (static or 
dynamic) to set up the VPN tunnel. 
!! Cannot find IPSec SA
The ZyWALL cannot find a phase 2 SA that corresponds with the 
SPI of an inbound packet (from the peer); the packet is dropped. 
!! Cannot find outbound SA 
for rule <%d> 
The packet matches the rule index number (#d), but Phase 1 or 
Phase 2 negotiation for outbound (from the VPN initiator) traffic is 
not finished yet. 
!! Discard REPLAY packet
If the ZyWALL receives a packet with the wrong sequence number 
it will discard it. 
!! Inbound packet 
authentication failed 
The authentication configuration settings are incorrect. Please 
check them. 
!! Inbound packet 
decryption failed 
The decryption configuration settings are incorrect. Please check 
them. 
Rule <#d> idle time out,

If an SA has no packets transmitted for a period of time 
(configurable via CI command), the ZyWALL drops the connection.
