AdGuard Home, opkg and ping on router not working

[Hailvid]

Hey, everybody. I installed AdGuard Home on my router (Asus RT-AX1800U) following these instructions from the wiki:
https://openwrt.org/docs/guide-user/services/dns/adguard-home
In general everything worked, but I encountered the same problem as the author of this post: Cannot update opkg after installing adguard.
Internet works, but when I try to run any opkg command from the router itself or just ping any site, no packets are forwarded. The author of the post above solved the problem by moving AGH to port 5353, left DNSmasq on 53 and enabled DNS forwardings to 192.168.1.1#5353, but in this case AGH sees only one client in its interface, namely 192.168.1.1, which significantly limits its ability to keep statistics.

Help to understand how to leave AGH to listen to port 53, and DNSmasq 54, and at the same time restore the connection of the router with the Internet. I suspect that the problem is port forwarding, but my experiments with this did not give anything. Thanks in advance!

executed on the router, post the output of ping 8.8.8.8, and nslookup forum.openwrt.org
post your /etc/config/firewall file..

Ping 8.8.8.8:

nslookup forum.openwrt.org:

/etc/config/firewall file:

Ping google.com:

you need to make AGH listen to 127.0.0.1 too,
or use some other, external, DNS for the router itself,
or start dnsmasq on 127.0.0.1, only.

as a temp workaround, you could try echo "nameserver 1.1.1.1" >> /etc/resolv.conf.

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:

@Hailvid

dns:
  bind_hosts:
    - 192.168.1.1

add - '127.0.0.1' here
you could also replace 192.168.1.1 with 0.0.0.0.

https://github.com/AdguardTeam/AdGuardHome/wiki/Configuration#configuration-file, scroll down to dns.

Thanks, that helped! I added the 127.0.0.1 address with the second line and now ping and opkg works.

dns:
  bind_hosts:
    - 192.168.1.1
    - 127.0.0.1

Thank you all for your help!
