Wendell, what does #netstat -rn say? Also, if you run tcpdump listening
on the alias IP address, do you see the ingress traffic from the remote
workstations? ie:

stewie# netstat -rn | grep 192.168.112.181
192.168.112.181 00:15:17:16:bf:9a UHLW 1 121 lo0 =>
192.168.112.181/32 link#1 UC 0 0 em0



# tcpdump -n -i em0 host 192.168.112.181



ping for another host:

stewie# tcpdump -n -i em0 host 192.168.112.181
