Ok, I will.  But, I can tell you that attempting to ftp THRU the Linux
NAT box from others (sic--not NetBSD) DO NOT kill the link.  I'd expect
this to be much the same, but I'll get setup and try it just to see what
happens.  Also, keep in mind that the up to date IP_masq code does handle
ftp properly; or, its supposed to anyway.
