All clients showing as localhost in AdGuard Home

Renato · 2024-08-07T08:44:37.254Z

I have this option enabled and I only can see "localhost" on the list since the beggining.
I recently noticed this because on GL-B3000 the list is by IP

MT6000:
No VPN, no Parental Control. It's running only Adguard Home. I can see only "loalhost" on the list.

B3000:
VPN is on, no Parental Control, also Adguard Home is running. I can see the IP list.

Please let me know your MT6000 firmware version and ADG version.
I have not reproduced this situation in FW v4.6.2, ADG v0.107.46.

To be honest, since I'm using MT6000, I never saw the list of IPs.
It's always "localhost", no matter the version of the firmware and AGH.

Current Flint2 firmware: 4.6.2
Current AGH version: 0.107.52 (update from here)

Could you please convenience to reset the firmware to see if this situation still there?
My configuration is same to yours, but it can not reproduce.

Another issue:
When I set some client to not use VPN, it can no longer perform nslookup...

I'm rapidly losing faith in GL-iNet's QA process... Every single update breaks some feature... I've delayed my update until now... and I got burnt once again when I push the update button.

This does not make sense tbh.

How do you run nslookup? Against local router or other servers?

briar-spoon-celibate · 2024-08-11T17:14:42.903Z

Hi @admon

What I'm trying to do is to

By Pass VPN by MAC Address
On the machine that have VPN bypassed, I ran the following and all failed

nslookup google.com
nslookup google.com 192.168.8.1
nslookup google.com 1.1.1.1
nslookup google.com 9.9.9.9

Did you running dhcp in adguard home or gl router?
Show me your client list in adguard home > settings > client setting

@slesar I'm running DHCP on GL Router.

The clients you see here (Source ARP) are from BEFORE the upgrade. They're no longer appearing on AdGuard Home. They now only show up as 127.0.0.1

If I uncheck everything under #/dnsview, all DNS requests bypasses AdGuard Home.

slesar · 2024-08-12T05:03:27.989Z

Can you show me firewall in luci (network > firewall > port forward), thanks.

Try uncheck 2 vpn dns and remove 2 unnames.
Looks like conflict dns port listens...

@admon would you be able to point me to the correct resource?

It worked (Somewhat).

After unchecking dns for vpn and dns for vpn guest, AdGuard Home shows the client IP address instead of localhost

I then go to VPN Dashboard of GL-iNet (/#/vpndashboard), updated the Proxy Mode from Global Proxy to Based on Client Device. Checked the VPN on the device that is on the exclude list, it can successfully do DNS look ups and bypasses VPN no problem. However, ALL dns requests to AdGuard Home now show as localhost. Even after I revert the Proxy Mode to Global Proxy doesn't help.

I then navigate to /cgi-bin/luci/admin/network/firewall/forwards, changed nothing but clicked Save & Apply and Voilà! Client IP now show up in AdGuard Home again...

felixna · 2024-10-23T17:01:04.099Z

I could solve my problem that only localhost / 127.0.0.1 was shown as client by cleaning up the firewall settings as suggested by @slesar , but now I have only IP adresses without hostname in the AdGuard Home log and also the top client list:

Any idea how I can display the hostnames next to the IP address again?

hostnames in luci (cgi-bin/luci/admin/network/hosts; Network > Hostnames)

Somehow turning AdGuard Home off and on again solved my issue at first.

Without VPN I had it already running perfectly: AdGH showed IP with hostname and local LAN hosts connected via DHCP were visible in DNS (provided by AdGH without manual entering the name).

Sadly that all broke now after I tried to setup a WireGuard Server to connect from my smartphone and I cannot bring it back to life even after disabling VPN. I try to figure out the reason.

@slesar I wanted to avoid manual setup of all local hostnames, since (with a few exceptions of static IP services) they should already be known by Flint2 when they get their network via DHCP by the Flint2 router.

slesar · 2024-10-24T08:34:05.863Z

Yes correct. Adguard home listen in luci DHCP. You could turn off DHCP in luci/LAN network range in GL gui and turn on Adguard home DHCP server. Should be auto name each devices🤔

Nosferatu · 2024-11-06T22:26:09.751Z

you're at the same point that I'm. So question: if from Lucy -> /luci/admin/system/startup we set a restart for Adguard service, it should work right ? ( in case you have scheduled a reboot at midnight) but from my side it didn't work, the command I set is: "/etc/init.d/adguardhome stop" then ....start but nothing happened. Tonight I will set it twice just for testing then I'll let you know, if someone have any workaround I'll be pleased, thx.

admon · 2024-11-07T06:11:39.724Z

You need to a add a cronjob for periodic restart. Startup scripts won't help at this point.

Via SSH run crontab -e and follow [OpenWrt Wiki] Scheduling tasks with cron
