If you have the keys for both hosts in your ~/.ssh/known_hosts file,
ssh doesn't complain at all, even with host checking enabled.

The fun part is getting both entries into the file in the first place.
I've been known to use methods like "mv ~/.ssh/known_hosts
 ~/.ssh/known_hosts.tmp ; ssh new-forwarded.host ; cat
 ~/.ssh/known_hosts.tmp >> ~/.ssh/known_hosts ; rm
 ~/.ssh/known_hosts.tmp" and simply cutting-n-pasting with a text
editor.
