NFTables use scripts to create tables and chains
...
To hardcode table and chain creation and deletion makes it impossible
for existing firewall infrastructures to integrate miniupnpd.
NFTables will either reevaluate packets through miniupnpd or
it will delete existing tables when there are already custom chains in it.

NFTables make tables name configurable
...
Right now the table names are hardcoded and do not integrate with an overall
firewall strategy.
NFTables has restrictions on how packets are evaluated against chains.
For example if multiple forward chains are evaluated with different prioity,
all packets that pass the first one will be reevaluated again in the second chain.
To have an overall firewall concept with miniupnpd it is necessary to use existing
tables and hence to configure them in miniupnpd.

NFTables use inet nat chain
...
NFTables supports inet in the nat chain as well.
Use it instead of IPv4 chain so it is consistent with the filter chain.
