set interfaces dummy dum0 description 'Dummy for incoming IPv6 traffic'
set interfaces dummy dum0 mtu 1500
set interfaces dummy dum0 address fdb4:5ed0:c509::1/48
set nat66 destination rule 8 description 'Public fixed IPv6'
set nat66 destination rule 8 inbound-interface name 'pppoe0'
set nat66 destination rule 8 destination address xxxx:xxxx:41:c000::1
set nat66 destination rule 8 translation address fdb4:5ed0:c509::1
```
When I try to do
```
delete nat66 destination rule 8 inbound-interface name 'pppoe0'
commit
```
I get
