10. FAQ
I can’t get from internet on equipment, which is connected to router and I have NAT
enabled.
The device's gateway has to be configured as the router.
Router resets itself, connection on Ethernet fails.
It is necessary to use an antenna, which will be situated far from power supply.
I don’t get on web server at NAT.
The remote http access of the router has to be disabled, default server address
has to be your web server and the gateway of the web server has to be the IP
of router.
PPP connection fails.
Check signal power. If signal power is weak, you will have to use a better
antenna. If the environmental cells have a similar signal it will be necessary
to use a directive antenna. Signal levels have to be in the range -50dBm and -
90dBm.
It is necessary to set ping, which will check the connection and, in the case of fail
ping, restart connection.
PPP connection won't be established.
Recheck GPRS settings - APN, name, password and IP address.
Try to enter PIN – verification if the SIM card hasn’t set PIN code.
In private APN it is appropriate to switch the DNS server send off.
Switch log system on and observe where the error turns up.
Connection fails on Ethernet or connection isn’t establishing.
On ethernet interface of the router it is possible to switch auto negotiation off and
set a rate and duplex by hand.

If the same IP address is recorded in your canonic name as dynamically assign
address, it means that the operator is using NAT or firewall.
NAT is possible to verify by the help of the ping on address of your server with
static IP address and by the help of the router address verify and address in ping.
Firewall is possible to verify, for example by remote access on web interface.
