This router supports armv7 architecture, however the linux_armv7 binary will not run on it. The solution is simple: use the linux_armv5 binary instead.
The DHCP "DNS Server" settings must be set to "Auto", so LAN clients' DNS will be set correctly.
Having static DNS (see image below) setting with external DNS servers causes client requests not routed to ctrld listener.
Policy-Based Routing is a feature that allows UDM users to route traffic to specific destination based on the source of the traffic.
When Policy-Based Routing (PBR) is implemented on the network, firewall rules are typically configured to redirect DNS requests to the dnsmasq instance associated with the WAN interface. However, this dnsmasq instance operates with a configuration specifically generated for WAN connectivity, limiting the ability to persistently integrate ctrld's configuration. Consequently, client DNS requests will not be routed to the ctrld listener.
To resolve this, users must either modify the existing firewall rules or create new rules with higher priority to direct DNS traffic to the ctrld listener. Modifying UDM configurations directly, outside of the web interface, carries significant risk and is not officially supported. Such modifications may lead to system instability or failure, and should be undertaken with extreme caution.
