NAT has state that needs to be tracked for packages to be routed correctly. The state memory is limited, so at some point it will be dropped and you will get the famous "connection reset by peer" which has been plagueing the internet for the last decades.
Do the same with IPv6, omit the NAT, and you do not need to keep that state in sync. P2P applications stop being a routing/port forwarding problem and are only a matter of firewall settings. Cut away all that SIP and IPsec debugging.
