 perhaps some more information would help:
 I'm experiencing this on two different boxes with totally different hardware, one located at datacenter and connected via LAN and second one that is sitting on ADSL line. 
 I have tried all sysctl variables that I could find remotely related to this with no luck, tried compiling kernel with and without DUMMYNET
 
 This are  kernel customizations I use:
 options         IPFIREWALL
 options         IPFIREWALL_VERBOSE
 options         IPFIREWALL_VERBOSE_LIMIT=100
 options         DUMMYNET
 options         HZ=1000    # strongly recommended
 options         IPDIVERT
 options         IPSTEALTH               #support for stealth forwarding
 
 options         ACCEPT_FILTER_HTTP      # Must be here or AcceptFilter won't work w/Apache2
 options         DEVICE_POLLING          # Imporoves network driver performance
 options         ZERO_COPY_SOCKETS
 device          coretemp                # On-die temperature sensor on Intel Core and newer CPUs
 
 
 Is it at least possible to turn of this checks for local IP's - it is most disturbing that I'm getting droped packets at apache jail to mysql jail communication?
