Subject:   accessing an outside IP from inside a NAT net

I'd like a hand figuring out how to access resources on the internal side
of a NAT net from within it without doing something kludgey with DNS.
i.e. suppose I run natd with a configuration like this:

# begin /etc/natd.conf
use_sockets
same_ports
port 8668
deny_incoming no
log
redirect_port tcp 10.0.0.128:80 206.169.18.10:80
# end /etc/natd.conf

Now if the DNS for the web server www.foo.com running on 10.0.0.128
directs a browser on the 10.0.0.0 net to 206.169.18.10, it doesn't get
routed back to 10.0.0.128; it just hangs (I'm acutally not sure what's
happening there, the connction never succeeds). Is there a nice way to
handle this case without running a dummy DNS just for the 10.0.0.0
internal net?

thanks,
-Ian
