I have a Freebsd box that has had just one IP address for a long time. I 
am trying to add another to run a website with it's own IP, ssl cert, 
etc. I've added IP addresses to boxes before without problem, but either 
this box has a problem, or I've forgotten something important (probably 
the latter.)

on# uname -a
FreeBSD on.identry.com 7.2-RELEASE FreeBSD 7.2-RELEASE #0: Fri May  1 
07:18:07 UTC 2009     
root@driscoll.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC  amd64

I have the new address (66.111.0.251) configured:

on# ifconfig
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
     options=19b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4>
     ether 00:0e:0c:ea:af:c2
     inet 66.111.0.250 netmask 0xffffffc0 broadcast 66.111.0.255
     inet 66.111.0.251 netmask 0xffffffff broadcast 66.111.0.251
     media: Ethernet autoselect (100baseTX <full-duplex>)
     status: active

The interface responds to pings:

$ ping 66.111.0.251
PING 66.111.0.251 (66.111.0.251): 56 data bytes
64 bytes from 66.111.0.251: icmp_seq=0 ttl=20 time=16.474 ms

And IFF I am logged into the server I can access the website using lynx, 
or by using telnet to access the page:

on# telnet test.gradedstamps.com 80
Trying 66.111.0.251...
Connected to test.gradedstamps.com.
Escape character is '^]'.

     Hello, world

However, I cannot access the website from outside the box, even with PF 
turned off:

~ 510 $ telnet test.gradedstamps.com 80
Trying 66.111.0.251...
telnet: connect to address 66.111.0.251: Connection refused
telnet: Unable to connect to remote host
~ 511 $

I'm stumped. Can anyone give me a clue where to look next?

Thanks:  John
