hm - sounds like a duplex problem?

*) whats the distance between Linux and FreeBSD box?
*) check network counters:
    linux: ifconfig
    FreeBSD: netstat -nia
              look for errors
    check switches between (or as far as possible) for full duplex, also 
FreeBSD (ifconfig)
*) check and compare tcpdump

Kind regards,
