I'm changing providers and in preperation I'm trying to implement a RUT950 as a backup WAN.
I've connected the Ziggo modem to the RUT950 through the WAN-port, set the RUT950 WAN-port to use DHCP.
I gave the RUT950 (LAN) a fixed IP (IP 10.10.10.1) and connected LAN1 to the WAN-port of my UniFi UDM.
I gave my UniFi UDM WAN-port a fixed IP (IP 10.10.10.2, Subnet 255.255.255.0, Gatewat 10.10.10.1) and the LAN of my UniFi UDM is 10.25.x.x.
In the settings of the RUT950 I've enabled WAN failover to use cellular as the failover.
I can't access the internet through my wired connection, what have I missed.
