I believe the answer to your first question is answered in the first post of this thread. And quite possibly the second question is as well. You may need to roll up your sleeves and dive into
unbound_manager advanced

Sorry to ask again. I have gone through the first thread as well as advanced menu - but cannot find the answer.
I cannot figure out "how to find out in Unbound which domains are being blocked for a particular client IP address?".
As a comparison, in Diversion, I can launch Diversion, F, 4, <Client IP address>.
This starts a tail-f of the log but only shows the blocked domains of the specific client IP.
I can then exit out of tail and in Diversion, el, 1, 1, <domain name identified from the tail-f>
Process the lists; and the domain is whitelisted.
How do I replicate this behaviour in Unbound?
- Finding out for a particular client IP what is 'being blocked'?
- Adding the 'identified blocked domain' to whitelist?
What exact commands do I launch or menu options do I choose in Unbound?

I'd use unbound_manager 'Advanced' command 'ea'
Code:
i = Update unbound and configuration ('/opt/var/lib/unbound/') l = Show unbound LIVE (Loglevel=1) log entries (lx=Disable Logging)
z = Remove unbound/unbound_manager v = View ('/opt/var/lib/unbound/') unbound Configuration (vx=Edit;vh=help)
x = Stop unbound vb = Backup current (/opt/var/lib/unbound/unbound.conf) Configuration
rl = Reload Configuration (Doesn't halt unbound) e.g. 'rl test1[.conf]' (Recovery use 'rl reset/user')
? = About Configuration oq = Query unbound Configuration option e.g 'oq verbosity' (ox=Set) e.g. 'ox log-queries yes'
sd = Show dnsmasq Statistics/Cache Size s = Show unbound Extended statistics (s=Summary Totals; sa=All; http://10.88.8.1:80/)
adblock = Install Ad Block [uninstall | update | track]
DisableFirefoxDoH = Disable Firefox DoH [yes | no] youtube = Install YouTube Ad Block [uninstall | update]
Stubby = Enable Stubby Integration DoT = Enable DNS-over-TLS
firewall = Enable DNS Firewall [disable | ?]
bind = BIND unbound to WAN [debug | disable | debug show] vpn = BIND unbound to VPN {vpnid [debug]} | [disable | debug show] e.g. vpn 1
scribe = Enable scribe (syslog-ng) unbound logging ad = Analyse Diversion White/Block lists ([ file_name [type=adblock] ])
dnsmasq = Disable dnsmasq [disable | interfaces | nointerfaces] ea = Edit Ad Block Allowlist (eb=Blocklist; eca=Config-AllowSites; ecb=Config-BlockSites; el {Ad Block file})
dumpcache = [bootrest] (or Manually use restorecache after REBOOT) ca = Cache Size Optimisation [ min | calc ]
views = [? | uninstall] | {view_name [? | remove]} | {view_name [[type] domain_name[...] | IP_address[...]] [del]} ]
dig = {domain} [time] Show dig info e.g. dig asciiart.com lookup = {domain} Show the name servers used for domain e.g. lookup asciiart.eu
dnsinfo = {dns} Show DNS Server e.g. dnsinfo dnssec = {url} Show DNSSEC Validation Chain e.g. dnssec www.snbforums.com
links = Show list of external URL links
[Enter] Leave Advanced Tools Menu
e = Exit Script [?]

If unbound logging is enabled, use command 'l' to view the log in real-time .....(if you have enabled @juched's statistics GUI, then you may see the results there or either grep the unbound log or create an SQL query against the database)
Unfortunately, by default unbound receives DNS requests from dnsmasq, (rather than individual LAN devices) so the source IP will always be 127.0.0.1.
e.g. an unidentified LAN device is requesting a blocked ('always_nxdomain') domain 'ipid.shat.net'

managed to resolve vpn query issue. the error was when i selected the vpn dns query option worked fine but not really! During the dns query, the ip address and host assigned by the ISP appeared. not vpn ip. I used it this way for a long time and then I realized the problem was caused by the settings of the vpn client. The Force Internet traffic through tunnel set policy rules was set because I used 1 client on this vpn client. i changed NO and my dns ip address became vpn 
. I use 2 vpn providers on one with only the dns resolution going on the other on the internet. So if the policy rules in the setting of unbound vpn is not working properly.

unbound_manager simply attempts to identify the IP address of the appropriate VPN interface...managed to resolve vpn query issue. the error was when i selected the vpn dns query option worked fine but not really! During the dns query, the ip address and host assigned by the ISP appeared. not vpn ip. I used it this way for a long time and then I realized the problem was caused by the settings of the vpn client. The Force Internet traffic through tunnel set policy rules was set because I used 1 client on this vpn client. i changed NO and my dns ip address became vpn
e.g. crudely using
Code:
ip route | grep "dev tun1"${VPN_ID}Back in April 2020, @Chris0815 shared/proposed his method, and posted several informative explanations
such as this
and is/was happy with the pros and cons of his method.
Clearly in the interim 6 months, unbound has been upgraded (two major releases - 1.10 and 1.11?), so it could be that unbound is now only using the WAN interface?
P.S. I recall you weren't convinced back in April 2020 that @Chris0815's solution worked?
it successfully identifies the vpn ip address, this is not the problem. the router's internal vpn rule system is a problem. Now I can see that the traffic on the vpn 2 interface has increased significantly compared to the previous period, now I think it works 100% well.
az érdekes, hogy ezt a dns ip címet a vpn szolgáltatótól kapom, ami nem az eredeti vpn ip cím. nem tudom mi folyik itt ez egy PTR DNS-cím
ez egy PTR DNS-cím" However, if you use a VPN Client, then you may opt to force unbound to bind to the VPN tunnel, so all unbound's DNS requests will be via the tunnel, so now your VPN assigned IP will be shown in a DNS Leak test. "
How do I force unbound to bind to the VPN tunnel? Because even when I use vpn client, it shows my WAN IP as my DNS server and not the vpn's IP.
How do I force unbound to bind to the VPN tunnel? Because even when I use vpn client, it shows my WAN IP as my DNS server and not the vpn's IP.
On the VPN page? I have policy rules set to "Policy Rules (strict) " to force only specific devices through vpn. I set it to policy rules without strict and still it shows my wan IP.
On DNS conf on the vpn page I set "Strict" or should I set it to exclusive or maybe disable it?
just try setting it to NO. and just set the unbound. and YES (all client use vpn) may work, but policy rules can cause confusion. I can only experiment further in the afternoon. But the fact that for me the dns ip changed until then was the wan ip.
I redirected all traffic to a single vpn server (client 1). Accept DNS Configuration: disabled, Force Internet traffic through tunnel: yes. I redirected the unbound server to a query via vpn 1. The result is my dns and ip address are the same, no dns leaks, ad blocking works all over the network! Query statistics and cache work well! The system has not worked so well yet. Everything I wanted now works!
there are so many errors that in this form the unbound_ manager advanced in ssh vpn 1 command shows the good internal ip address of tun11 but does not write it to the unbound.conf file and thus does not update it (outgoing-interface: 10.8.8.9). only updates if Force Internet traffic through tunnel: policy rules is set. i don't understand why ??

No idea why you deliberately chose this contentious statement as your opening gambit
"there are so many errors......."
Not really the way to elicit support is it? but I'd appreciate a comprehensive list of the "many errors" so I can hang my head in shame.If you run unbound_manager with 'debug' , it should produce output to display the two 'sed' commands I use to update the 'out-going-interface' direcective in 'unbound.conf'

Get a room guys....but post the results, of course.
you are funny! Bind disabled and all traffic redirect to vpn, no policy rules!! and check your DNS.Get a room guys....but post the results, of course.

I am confused about what should happen when routing DNS requests though a VPN
1. What DNS server should be visible for a device NOT using the VPN
2. What DNS server should be visible for a device using the VPN
Using bowserleaks.com/ip to check for the DNS address.
Enable DNS-based Filtering = Router
unbound set to use VPN 5
On the VPN 5, I set Policy Rules = Strict (with a list of devices using the VPN) and tested with both Accept DNS = Exclusive and Disabled
If Accept DNS = Exclusive then
Device not using VPN: DNS = Router IP address
Device using VPN: DNS = VPN assigned IP address
If Accept DNS = Disabled then
Device not using VPN: DNS = Router IP address
Device using VPN: DNS = Router assigned IP address
Is this what I should expect?
