Thanks so much for the suggestion.  When I use passive mode I get an error
message "Could not open ftp connection to ftp3.freebsd.org.  Service not
available, closing control connection."  When I hit OK another error message
comes up "unable to initialize selected media.  Would you like to adjust you
media configuration and try again?"  When I do that, I go through the
network configuration process again, but I get an immediate error message
"Cannot resolve host name ftp3.freebsd.org!  Are you sure that your name
server, gateway and network interface are correctly configured?"  I'm using
DHCP, and it is pulling the correct IP's for these.

Here's the log in my Winroute NAT.  What do you think I'm doing wrong?

This is where the install program quit and asked if I wanted to retry.

I'm almost sure MTU is not the problem in this case, the Windows machine
should be taking care of that. Try setting FTP into passive mode in the
installer's options screen, or turning off passive mode if that's the
default on your version. Windows 98 NATs are not famous for handling FTP
properly.
