Say your inside device has an address of 192.168.1.10. You want it to be
reachable from the outside via 1.2.3.8. Your 'outside' address of the
switch is 1.2.3.4. You can add a secondary address of 1.2.3.8 to that
192.168.1.10 host, so that it responds to that address. Now add a host
route to the switch - ip route 1.2.3.8 255.255.255.255 192.168.1.10. The
host route will be more specific than the connected route, so it'll send
anything with an destination address of 1.2.3.8 to the 192.168.1.10 host.
The host will respond with it's 1.2.3.8 address as a source, so it should
work fine. Just make sure your switch isn't doing any reverse path
verification, as it'll make it fail.
