Hi all!

I'm running FreeBSD 4.5 RELEASE on a multi-homed host.  Output from netstat, 
ifconfig and parts of the syslog file follow.  NIC one is on PCI slot 2 (sis0) 
and NIC two is on PCI slot 3 (sis1).  Reseating and swapping did not help me to 
gain connectivity through the sis1 interface.  Any thoughts?

Thanks in advance for any assistance you can provide.

Dan Auman
