I have RT-AX3000 running Asus Merlin 3004.388.5 which was working fine till today, now all my devices cannot connect to the internet via IPv4 (somehow IPv6 is working)
- I haven't changed any configurations for the past month
- Last upgrade was more than one month (from 3004.388.4)
- Router is assigned IPv4/IPv6 through PPPoE
- I've disabled IPv6 and restarted, same issue persisted
- Router can ping internet IPv4 just fine, while other WiFi/Ethernet clients can't
- DDNS is updated successfully
- I can connect to the router VPN server from different network (but no Internet connectivity for the client)
- I noticed that the nat-start script is not starting
- I've restarted the router multiple times
