9. FAQ
¾ I can’t get from the internet on equipment, which is connected to the router and I have
NAT enabled.
 The device's gateway has to be configured as the router UR5.
¾ Router resets itself, connection on Ethernetu fails.
 It is necessary to use an antenna, which needs to be far from the power supply.
¾ 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 UR5.
¾ PPP connection fails.
 Check signal power. If signal power is weak, you need to use a better antenna.
If the environmental cells have similar signal it will be necessary to use
a directive antenna.
 It is necessary to set ping, which checks the connection and in the case of fail
ping restart the connection.
¾ PPP connection won't be established.
 Recheck PPP 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.
¾ Connection fails on Ethernet or connection isn’t establishing.
 On ethernet interface of the UR5 it is possible to switch auto negotiation off
and set a rate and duplex by hand.
¾ DynDNS does not function.
 In private APN not functional.
 If there is recorded the same IP address as your canonic name and dynamically
assigned address, means that the operator is using NAT or firewall.
 NAT is possible to verify by the help of ping to a random address of your server
with a fixed IP address and by the help of the UR5 control address and address
in ping.
 Firewall is possible to verify for example by remote access on the web interface.
