tcp problem with freebsd 7.1?

[Wes Zuber]

We have had some issues with NIC drivers in the past.. what Nics are  
you running. Specifically some Nics need to have the CRC checks  
disabled.

This also sounds like state is not being kept on the IP Filter if you  
are running one. Do you have more details?
