Why good ones. NAT is a basic IPv4 firewall. All IPv6 needs to obsolete
NAT is a firewall that offers all the features of NAT without requiring
the address translation. Then, instead of setting up a port translation
for a particular incoming protocol, you simply open up that port without
modifying the packets as they flow through. Suddenly, SIP works and
incoming VoIP phonecalls work just like on the phone network.
