Can I point 2 external addresses to 1 internal???

How do I do it and is there a sample config? Thanks in advance?

Re: Can I point 2 external addresses to 1 internal???

You cannot statically NAT 2 external addresses to one internal, although you can port translate 2 or more external address to one internal for different ports.

eg

external address 1.1.1.1 used for port 80

external address 2.2.2.2 used for port 23

internal address 192.168.1.1

static (inside,outside) tcp 1.1.1.1 80 192.168.1.1 80 netmask 255.255.255.255

static (inside,outside) tcp 2.2.2.2 23 192.168.1.1 23 netmask 255.255.255.255

above NATs 1.1.1.1 port 80 to internal 192.168.1.1, and 2.2.2.2 port 23 to same internal.
