Cisco to Sonicwall VPN - payload processing error 500 points to winner
Posted on 2006-06-19
We have a Sonicwall 4060 enhanced. A customer of ours is useing a CISCO firewall and we have setup a SITE to SITE VPN tunnel. The tunnel comes up and thier users are able to access our resources via telnet but then randomly they drop connectivity. I was looking through the logs on the VPN IKE and found that the following error messages showed up.
156 06/19/2006 05:50:07.080 Info VPN IKE Received IKE SA delete request 22.214.171.124, 500 126.96.36.199, 500
158 06/19/2006 05:50:07.080 Info VPN IKE Received IPSEC SA delete request 188.8.131.52, 500 184.108.40.206, 500 SPI:0x4441afce
160 06/19/2006 05:50:03.080 Error VPN IKE NOTIFY: -payload processing error 220.127.116.11(SOURCE), 500 18.104.22.168(DESTINATION), 500
When this happens I think is when people are getting randomly dropped. Any idea what these errors are caused from?
