Is the 3Com 590-COMBO? BG> TPO? I just installed a FreeBSD-based firewall bastion host using 3Com cards. In the first setup, I had a 3c590 and 3c595. The 3c590 interface kept having problems and filled up buffers after about 1700 or so bytes attempted to be sent through it. I'd need to bring the interface down and back up to clear the queue and restore buffer space. (Didn't have any software misconfigurations like messed up MTUs or anything...I did check :-) The 3c595 never had this problem. We swapped the 595 and 590, and the problem continued on the 590's interface. Got rid of the 590 and used a second 595, and it's been rock solid since. Very strange. I know very little about PC hardware (used to Sun, IBM RS/6000, and SGI hardware), so I'm not sure exactly what might have been going on below the OS... -- C Matthew Curtin MEGASOFT, LLC Director, Security Architecture I speak only for myself.
