As usual, the user is the biggest enemy of devices. I created a lot of firewall rules and got lost in them. My mistake, I deleted one entry and the problem was solved, the internet is working again. Thank you all for your help and sorry for the trouble.

I tried, but nothing changed.

I tried, same thing

I forgot to add the attachment. Diagnostics attached. tower-diagnostics-20251214-2203.zip

Unraid server (version 7.2.2, Ubiquiti Dream Router 7/UDR7) shows correct IP address via ip route show, but cannot connect to internet. Local network pings work fine (e.g., router, other LAN devices), but external pings (e.g., 8.8.8.8, google.com) fail. Changing DNS servers (tried 8.8.8.8, 1.1.1.1, ISP DNS) did not help. Why Pi-hole bridge works but host doesn't? Symptoms: ip route show displays proper local IP, subnet, and default route (via router IP, e.g., 192.168.1.1 dev br0). Ping to local IPs/hostname succeeds. Ping to external IPs/domains times out from host. Pi-hole Docker container (bridge mode) has full internet access (can resolve domains). Can access Unraid GUI locally via IP. No firewall/VPN active; Docker/VMs tested disabled. Network Setup: Router: Ubiquiti Dream Router 7 (UDR7), latest firmware. Unraid Network: br0 bridge, DHCP (also tried static). No VLANs, bonding, or custom routing initially. Tried: Reboot server/router, reset network settings, manual route add (ip route add default via [ROUTER_IP] dev br0 - temporary?).
