In your case two different subnets on two interfaces IMHO look much better. If you are sure about one-subnet setup than you should try to set up a bridge(4) between them two NICs. Bridge in FreeBSD is supporting ipfw filtering, so you can still complete your security goals. Thursday, September 02, 2004, 10:17:37 PM, rip wrote: r> Hello All; r> Here is the puzzle r> ??

Will this act as a switch (mac specific) or a hub (broadcast mode). -- Best regards, ; Nickolay A. Kritsky ; SysAdmin STAR Software LLC ; mailto:nkritsky@star-sw.com
