From your IP address and routing table, it seems has not problem. If you connect a PC to the router, can the PC get IP address and ping the router?

Could you ping 192.168.1.1? It's the GW of your R470T+. If you can ping 192.168.1.1, it means that R470T+ can forward the data normally. If not, R470T+ should has problem, check whether has some Firewalls rule on R470T+ which may block the data. If you can ping 8.8.8.8 but cannot access the internet, please check the DNS server for your devices and router.

From Client Box with ip 192.168.252.2, I can obviously ping R470T+ LAN Interface (192.168.2.254), and also WAN Interface (192.168.1.6)

But I can't ping the GateWay of WAN Interface (192.168.1.1) NOR internet (8.8.8.8)

For the Firewall Settings I haf no RULE I decided to create one which alllowed everything. Also in this part MAC Filtering is disabled.

ID    Name    Source                  Destination        Policy          ServiceType  Interface  EffectiveTime

1     default  IPGROUP_ANY     IPGROUP_ANY  Allow           ALL                ALL         Any

@ksxour 

 

Save your configuration and try to reset your router. If still has the problem, you can check the ARP table for R470T+ and its gateway. It's for confirming has not IP conflict.

For R470T+, you can access Firewall->Anti ARP Spoofing->ARP Table. You need to know the LAN MAC of R470T+'s gateway. Then confirm whether the ARP is correct.

 

You also can use wireshark to capture the packets for WAN port. But you need to know about wireshark and port mirror.

 

Maybe R470T+ did not forward the packets, maybe its gateway did not reply R470T+.
