I had the same problem with my opal, however wanted to be able to disable adguardhome for captive portals and easiest to have it on the gl.inet front end (so didn’t want to change default dns port etc), so i put the routing change into the service start stop action…
good point about the local dnsmasq hostname lookup, hadn’t considered that!
i also built a custom firmware with all my settings built into it which comes in handy if i’m messing with my router on holidays and break something… means i can just reset it back to the known working state… very handy!
/etc/init.d/AdGuardHome
start_service()
{
…
iptables -t nat -A PREROUTING -p tcp --dport 53 -j DNAT --to ROUTER_IP:3053
iptables -t nat -A PREROUTING -p udp --dport 53 -j DNAT --to ROUTER_IP:3053
}
stop_service()
{
…
iptables -t nat -D PREROUTING -p tcp --dport 53 -j DNAT --to ROUTER_IP:3053
iptables -t nat -D PREROUTING -p udp --dport 53 -j DNAT --to ROUTER_IP:3053
}

Hello guys today I switched the port from both services (dnsmasq and adguard) on GL-AX1800 kernel: 4.4.60. It’s working ok. Further info over my blog

Do you have a DHCP server running on a separate router, not the GL-AX1800? In your procedure, dnsmasq is disabled, so DHCP will not be running on the GL-AX1800?
I do not work for and I am not directly associated with GL.iNet

I don’t; I think I will list my steps over here it would be better (later I’ll edit it from my website):
Note: The following instruction has been applied into router below
- Router: GL-AX1800
- Kernel version: 4.4.60
It would be faster if you plug the computer with RJ45 wire.
Steps:
1- do a backup.**
2- connect on your device by ssh.
From here I supposed you have “dnsmasq” service up and running.
3- change dnsmasq port.
echo "port=5300" >> /etc/dnsmasq.conf
4- change port from Adguard config file
vi /etc/AdGuardHome/config.yaml
---
dns:
bind_hosts:
- 0.0.0.0
port: 53
---
5- stop dnsmasq
/etc/init.d/dnsmasq stop.
6- starts Adguard, go to Settings - DHCP Settings and startup DHCP service on Adguard.
7- disable dnsmasq
/etc/init.d/dnsmasq disable.
8- restart Router
Steps Explanation:
1- not explanation needed, do always a backup before a change.
2- ssh connection to your router.eg: ssh root@x.x.x.x
3- this will change the default port of DHCP service, not needed it but it would be better to apply it; cos at the end you will disable the service thus this port shouldn’t be use it.
4- set the port “53” to Adguard service.
5- as we won’t use it.
6- setup adguard service to be use as dhcp server
7- disable service as we won’t use it any more.
8- test if these changes are persisted.
From my side (Adguard):
root@GL-AX1800:~# netstat -pnlt | grep -E "53"
tcp 0 0 0.0.0.0:xxx 0.0.0.0:x LISTEN xxxx/xxxx
tcp 0 0 0.0.0.0:xxx 0.0.0.0:x LISTEN xxxx/xxxx
tcp 0 0 :::53 :::* LISTEN 8124/AdGuardHome
tcp 0 0 :::xxx :::* LISTEN xxxx/xxxx
tcp 0 0 :::xxxx :::* LISTEN xxxx/xxxx
Okay. I see that you are using the AdGuardHome DHCP server. It may not be necessary to change the dnsmasq port in /etc/dnsmasq.conf if you are disabling dnsmasq anyway.
To use the DHCP OpenWRT server on the router, it is okay to leave dnsmasq enabled.
