Your XR500 router does have public IPv4 address on it's WAN/Internet interface, or does your ISP (or in-house network service) deploy Carrier Grade NAT (RFC6598, or even worse private RFC1918) IPv4 addresses?

 

Compare the information shown on your router Web UI WAN/Internet port vs. a search for "what is my IPaddress"!

 

Is the XR500 connected behind another NAT router?

 

Any ISP side firewall provisions in place?

Effectively, the IP WAN address is private (10.x.x.x)

My modem is in bridge mode, I have any other routers except the XR500

 

So what should I do now ?
