VPN IPSec Troubleshooting 

4.1

 

« PAYLOAD MALFORMED

 

» error 

114920 Default (SA ZyWALL-P1) SEND phase 1 Main Mode  [SA][VID] 
114920 Default (SA ZyWALL-P1) RECV phase 1 Main Mode  [NOTIFY] 
114920 Default exchange_run: exchange_validate failed 
114920 Default dropped message from 195.100.205.114 port 500 due to notification 
type PAYLOAD_MALFORMED 
114920 Default SEND Informational  [NOTIFY] with PAYLOAD_MALFORMED error 

 
If you have an « PAYLOAD MALFORMED » error you might have a wrong Phase 1 [SA], check if the encryption 
algorithms are the same on each side of the VPN tunnel. 

4.2

 

« INVALID COOKIE » error 

115933 Default message_recv: invalid cookie(s) 5918ca0c2634288f 7364e3e486e49105 
115933 Default dropped message from 195.100.205.114 port 500 due to notification 
type INVALID_COOKIE 
115933 Default SEND Informational  [NOTIFY] with INVALID_COOKIE error 

 
If you have an « INVALID COOKIE » error, it means that one of the endpoint is using a SA that is no more in use. 
Reset the VPN connection on each side. 

4.3

115319 Default ipsec_get_keystate: no keystate in ISAKMP SA 00B57C50 

 
If you have an « no keystate » error, check if the preshared key is correct or if the local ID is correct (see 
« Advanced » button). You should have more information in the remote endpoint logs.
