^^^^^^^^^ this doesn't get you anything better. "real.net.ip"
will still have no idea who 10.0.0.99 is.
In should look more like
In [TCP] 10.0.0.28 -> some.real.net.ip:23 aliased to
Dialup.ip.real.address -> some.real.net.ip:23
Probably posting /etc/rc.firewall would be helpful.
are you starting natd with an interface switch? such as
natd -interface ppp0
easy to forget...
