General Discussion / Re: AdGuard - no client hostnames

« on: October 09, 2023, 04:55:32 pm »

a) Move AGH to OPNsense
b) Move DHCP to AGH
c) Do static mappings in AGH - Filters - DNS rewrites

a) Separate AGH seems to be more stable than the OPNsense plugin - I saw on this forum many people had issues recently because of updates to either OPNsense/AGH/AGH plugin on OPNsense - thankfully I never had any of those issues, plus I can easily backup/rollback AGH with no impact on OPNsense

b) I don't want to depend on AdGuard for anything more than adblocking. I like the idea that I can just replace AGH with say Pihole or something else and have close to zero impact on OPNsense.

c) This is what I currently do... and it gets very tedious after a while, especially when working with many devices and containers

reverse dns is working fine here.
have you checked if something is wrong with your adguard settings or blocked by firewall itself?

https://github.com/AdguardTeam/AdGuardHome/wiki/Configuration#specifying-upstreams-for-reverse-dns

Did you have to partake in some sort of black magic rituals to get this working, because I want in as well

I added the following to my upstream DNS servers in AGH

Code: [Select]

[/in-addr.arpa/]192.168.101.1
[/ip6.arpa/]192.168.101.1
127.0.0.1:53
127.0.0.1:8053And then 192.168.101.1 as the Private reverse DNS server.

For reference - AdGuard is running in VLAN_101 and its IP address is 192.168.101.12, and the gateway IP of that VLAN is 192.168.101.1

Code: [Select]

> nslookup 192.168.101.134
** server can't find 134.101.168.192.in-addr.arpa: SERVFAIL


> nslookup homeassistant.lan

General Discussion / AdGuard - no client hostnames

« on: October 07, 2023, 11:33:03 pm »

Hi, I am very new to OPNsense (recently moved over from OpenWrt) and I'm enjoying the upgrade very much 

I have an existing instance of AdGuard Home already running on a separate server in my network.
I was able to configure OPNsense to use my existing instance of AdGuard (not as a plugin) and everything works well, with one exception:

AdGuard does not see the hostnames in its dashboard.


I was hoping that someone may be able to point what I'm doing wrong, please:

AdGuard Home version: v0.107.38 (latest)

DNS Settings:

• Upstream DNS servers:   127.0.0.1:53 & 127.0.0.1:8053
• Parallel requests:   Yes
• Fallback DNS servers:   None
• Private reverse DNS servers:   Gateway_IP
• Use private reverse DNS resolvers:   Checked
• Enable reverse resolving of clients' IP addresses:   Checked

DHCP Server:   Disabled in AdGuard (I am using the DHCPv4 from OPNsense; IPv6 is disabled across the network)


OPNsense version: 23.7.5 (latest)

System\Settings\General:

• DNS servers:   ADGUARD_IP   |   Use gateway: No
• DNS search domain:   None
• Allow DNS server list to be overridden by DHCP/PPP on WAN:   Unchecked
• Do not use the local DNS service as a nameserver for this system::   Checked
• Allow default gateway switching:   Unchecked

Services:

• Dnsmasq DNS:   Enabled: No
• OpenDNS:   Enabled: No
• Unbound DNS:   Enabled: No

OPNsense FIrewall rules (NAT):




OPNsense Firewall rules (ALL_LOCAL) - which represents my local and trusted VLANs:




Despite all devices having a hostname by default, I also provide it in OPNsense's DHCP lease for static clients, yet AdGuard does not see any of it:




Any thoughts on how to get the client hostnames from OPNsense to also propagate over to AdGuard?
