I am getting the following error messages continously in my PIX 535 firewall.
Why its happening and How to solve this issue. This logs are coming for some other IPs also.
Jun 04 2012 01:09:46 blr-dcvsnl-cp535-01 : %PIX-4-313003: Invalid destination for ICMP error message: icmp src PIX-Alteon:10.1.240.11 dst inside:10.1.18.96 (type 3, code 1) on PIX-Alteon interface. Original IP payload: tcp src 10.1.18.96/22 dst 10.1.240.69/1243
So it confirms no issue with PIX. or anything to be checked from PIX side?
Because the messages are generated for Checkpoint firewall, Cisco VPN gateway, F5 Load balancer, VLAN interface of Cisco 4507 Switch. NO server or no hosts involved in this.
How to troubleshoot this?
In that case, you could have been hitting bugID: CSCsc97999
