Sophos Configuration - FiberONE ISP

Hi All,

I have a Internet Link from FiberOne ISP. I used a media converter to convert the Fiber link to Rj45. Then I plugged it into a ASUS DSL Modem/Router to use Wifi. in this situation, I got IP Address A, and I have the internet. But, I have a lot of attack on my link so I decided to buy Sophos SG125 and I Updated Sophos Firewall to XG OS version 20.0.0_GA-222(The latest update). then I Configured eth1 as an DHCP configuration and Plugged Rj45 link that come from Media Convertor Directly. after that I saw eth1 gave new IP address B that is different from IP  address A(so it means FiberONE assigned IP on DHCP Mode for any new device that directly connected to the link.) So I dont have internet in this condition.
The problem is in this condition I check Wan Link Manager and see IPV4 gateway status is Down(Red) and IPv6 Gateway status is up(Green).
I sent Ticket to FiberONE ISP Support and the answer was, update your Sophos Firmware and sure your Firewall support Host Routing :))
So anybody can help me? is there any addittional configuration that I must set on my Sophos or it is the problem on ISP side?
