I'm trying to NAT through BorderManager to a web server that is bound to a
secondary IP address on an internal, private server. I can connect to the
same server's primary IP address fine...just can't get to the secondary IP
address web services.

NAT:
216.x.x.29 => 172.16.0.29 (connects OK)
216.x.x.92 => 172.16.6.92 (can't connect)

Server 172.16.0.29 has a secondary IP address of 172.16.6.92 on which the
web server is bound.

Any ideas what I might be missing?
