Are you using PPPoE or some other sub 1500 MTU connection from the 
NetBSD NAT box?  The NAT machine itself working, but the machines behind
it failing suggests MTU issues to me.

I personally don't have this problem on my home system running -current
with NAT.  

But.. the '230-<new line>' chokes Firewall One systems, for example,  that
don't have the strict checking disabled.

I don't know if this can be fixed on the ftp server or not, just to work 
around some broken systems out on the net.
