Hello, I followed this link to configure a 1605 router to CheckPoint 4.1: http://www.cisco.com/warp/public/707/cp-r.shtml My network is: 192.168.2.1-(1605)-16.191.40.99----16.191.40.39-(checkpoint)-192.168.1.1
VPN tunnel could not established, here is the debug output from 1605 router: 00:01:29: ISAKMP: reserved not zero on payload 5! 00:01:29: %CRYPTO-4-IKMP_BAD_MESSAGE: IKE message from 16.191.40.39 failed it s sanity check or is malformed 00:01:29: ISAKMP (1): sending packet to 16.191.40.39 (I) QM_IDLE 00:01:29: ISAKMP (1): received packet from 16.191.40.39 (I) QM_IDLE 00:01:29: ISAKMP: reserved not zero on payload 5! 00:01:29: ISAKMP (1): sending packet to 16.191.40.39 (I) QM_IDLE 00:01:29: generate hmac context for conn id 1 00:01:29: ISAKMP (1): deleting SA Looks like there is something wrong on the CheckPoint. Log was turned on at CheckPoint but didn't capture any info. Is there anything wrong with Cisco sample configuration? Or anything I missed? Thanks in advance.
