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 interface router. If this choice isn't selected and is selected volition Send all

remaining incoming packets to the default server fulfill oneself connection on induction IP

address. If it is not selected election Send all remaining incoming packets to default server

and Default server IP address then connection requests a failure. If it is necessary to set

more than 8 rules for NAT, then it is possible to insert into start up script following script.

If necessary set more than twelve rules for NAT, then is possible insert into start up

script following script:

iptables -t nat -A napt -p tcp --dport [PORT_PUBLIC] -j DNAT --to-destination

[IPADDR]:[PORT1_PRIVATE]

Concrete IP address [IPADDR] and ports numbers [PORT_PUBLIC]

and [PORT1_PRIVATE] are filled up into square bracket.
