Hi I recently purchased XC220-G3V router to replace my old ISP provided OTN. 

I did the GPON registration which was completed successfully and I used the MAC address of my old OTN during the WAN registration, everything looks fine and connected but I'm not able to access the internet. I've attached some screenshots of the router settings below. Some solutions to rectify this issue is well appreciated as my ISP is not willing to help in this matter.
