Unhappy ssh port forward failure


Hello all,

I have configured our iptables to forward a request to port 2223 on our server to my pc port nr 22. And that actually works if I have an empty know_hosts file on the remote machine I want to use to login to my machine. Something like: $ ssh -p2223 foo@bar.com
On connection ssh ask whether or not I would like to add a key to my empty known_hosts file. I agree and merrily go my way. But if I disconnect and try to ssh to our server like: $ ssh foo@bar.com it complains about "WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!" and "Host key verification failed". Real nice, now I have to clean out my known_hosts file again.
There must be an easier way! Can't I configure the remote system so that I will be able to connect to _both_ port 22 and 2223 without deleting the entry out of my known_hosts file?
Any help is appreciated.

Either turn off strict checking in ssh_config
or use an ip number for the non standard ports connections..
