Hi guys. I need urgent help. I am using a TP-Link MR3420 (ver 3) router. I have purchased a 3G dongle with an active data SIM card.

I checked my WAN IP and it is giving me 203.1xx.xxx.xxx. According to my ISP, it is a dynamic public IP address.

The problem is when I attempt to set remote access to my router using 255.255.255.255 and my own port number, I am not able to access it via another PC after typing the address of 203.xxx.xxx.xxx:xx.

Is there something wrong with my router configuration? Or is my ISP blocking something?

Please help! Thank you!
