As mentioned, sniff the traffic on WAN, while you try to access the IP and you will instantly know, if it even works on the outside and can go further.
Thx a lot but How to sniff the wan traffic?
Hi Patrick, Thx for reply. But I don't know how to show virtual IP configuration and your port forwarding rules. I can take snaps but cant find another way to get it. the rules were auto generated by NAT
