Maybe iptables?
Iptables can certainly be configured to do what you have listed above,
but not IMHO as easily nor as cleanly.  The syntax is different and so
somewhat harder to use.

However, that seems like throwing the baby out with the bathwater.  I
would think that having tcpwrappers (which is what uses the hosts.deny
and hosts.allow files) in effect was a good thing.
