I have searched with Google, and found the message below: http://docs.freebsd.org/cgi/getmsg.cgi?fetch=180949+0+archive/2002/freebsd-n et/20020707.freebsd-net It seems that bridge supports only NICs with "SIMPLEX" flag. Therefore, I checked result of "ifconfig -a", but my two Intel 82550 (fxp0, fxp1) has "SIMPLEX" flag: fxp0: flags=8943 mtu 1500 fxp1: flags=8943 mtu 1500 Any suggestion?
