In this configuration equipment wired behind the router defines the address Server IP
Address. The router replies, while PING on address of SIM card. Access on web interface of
the equipment behind the router is possible by the help of Port Forwarding, when behind IP
address of SIM is indicating public port of equipment on which we want to come up. At
demand on port 80 it is surveyed singles outer ports (Public port), there this port isn't defined,
therefore at check selection Enable remote http access it automatically opens the web
