I have got a RUT500 with 3G SIM card.
I have reset to factory default and have configured using the wizard.
I have setup the APN and have connectivity as I have internet access when connected via LAN Ethernet port.
I have DHCP enabled (as default)
I have wireless enabled (as default)
the only thing I have changed is the router static up address from 192.168.1.1 to 192.168.0.1.
I have a web server connected to another LAN Ethernet port with a static IP address of 192.168.0.131 which is using port 80
I am able to access the webpage on my laptop on internal IP 192.168.0.131.
I have tried making this accessible externally by going to Firewall > Port Forwarding; here I setup a rule for port 12345 on any external WAN to forward to port 80 on internal LAN 192.168.0.131.
When I go to the Network Status page and copy the WAN IP address into internet browser:
It works whilst connected via the LAN Ethernet port.
When I disconnect laptop and using a different internet connection, It does not work.
Please could someone help/advise?
Is this the correct WAN IP address? Does the sim card have to be configured to allow connections or something? Am I missing any firewall rules or router settings?
