M2M Gateway eth1 does not work?

A: Check that IP forwarding has been enabled and internal firewall does not
block packets.

Q: From Arctic Ethernet connection to M2M Gateway Ethernet is not working?

A: Check that IP forwarding has been enabled on Arctic.

Q: If only one public IP is available, can the M2M Gateway be used?

Common Problems

Problem #1

Q: Console does not receive characters.

A: Disable HW and SW handshaking from you terminal software (e.g.
Hyperterm or Minicom).

Problem #2

Q: GPRS interface is up but no traffic flows through it.

A: Default gateway in Ethernet settings submenu has to be set as “0” and also
default gateway has to be enabled from Network/GPRS menu when using
GPRS interface as the default gateway.

Problem #3

Q: GPRS connection is not established.

A: Check that the SIM card has the correct PIN number settings and that
it has not been locked after a wrong number was entered three times
successively. PIN status can be checked from Tools/Modem Info menu.

Problem #4

Q: GPRS connection is ended after approximately two minutes.

A: You have enabled connection checking from Network/Monitor menu but not
set the correct IP to GPRS “ICMP Echo settings”.
