BIND and DNS Forwarders to unbound (127.0.0.1)

[DomCa]

Hi all,

I would like if this configuration is possible:

I have a NAT rule for NATing from port 53 to port 53530 to use DNSBL for a group of IPs (childrens devices). The other IPs should be able to acces the internet without limitations.

In the unbound DNS I activated "Register DHCP leases" and "Register DHCP static mappings " to reach some local hosts in my network.

If I want to also enable this for the devices that are redirected to BIND, can I set the " DNS Forwarders" option of BIND to 127.0.0.1?

Thanks!
