I have 2 Mailservers,
Can I map 2 External IPs to the same Internal IP?


static (inside-HBG,outside-HBG) 192.168.1.8 10.1.0.9 netmask 255.255.255.255
static (inside-HBG,outside-HBG) 192.168.1.9 10.1.0.9 netmask 255.255.255.255

Seems logical to me.

The NAT translations will remain unique due to the external host's IP
address/source port combination, and the specific global NAT IP address
destination.

Hmmm.. I think I follow it, though not sure how/why you would need to
Expose the Private Address to the outside, I guess it would work if the 2nd
static statement was
172.16.171.126

Hmmm.. I think I might way for the DNS entry to time out on the remote
server... (-;

Thanks,
