Good morning,

I'd like to forward DNS requests in the public (internet) view for a subdomain that is hosted on a different DNS server.
Forwarding isn't supported when the settting 'recursion no' is used.
Therefore, changing the setting to 'recursion yes' makes it possible.

# (1) existing configuration
view "public" {
    allow-query { any; };
    match-clients { any; };
    allow-recursion { none; }; 
    recursion no;
....

# (2) new configuration
view "public" {
    allow-query { any; };
    match-clients { any; };
    allow-recursion { none; };
    recursion yes;
....

In configuration #(2) forward would be configured as follows:
zone "other.example.com" {
    type forward;
    forward only;
    forwarders { 10.10.10.10.10; 10.10.10.20; };
};

Bind is  ver. bind-9.16.23

Will configuration #(2) be secure?
Is there any risk of security violations compared to configuration #(1)?

Thanks,
Kazik
