Arctic GPRS Gateway
Firmware Version 5.0.7

Document Version 1.6
Host name – Sets the Arctic device hostname. This is important to set up
correctly when using a Viola M2M Gateway and VPN.
Every Arctic connected to Viola M2M Gateway must have unique hostname.
Domain name – Domain name for name resolution (optional).
Ethernet IP address – IP address used by eth0 interface.
Network mask – Network mask used by eth0 interface.
Use Ethernet as default route – Set this to “Yes” only when using Ethernet
as default gateway/router. This parameter overrides next parameter “Default
Route IP Address”, so as long this parameter is set to no, next parameter has
no affect. Usually this is set to “No”, because either GPRS on VPN is used as
default route.
Default Router IP address – Default router (or default gateway) used when
the direct route to host or network is not known. This parameter applies to
eth0 interface only. When GPRS or VPN is used as default gateway this
parameter has to be set to 0.
MTU – MTU for Ethernet interface (usually 1500).
DNS servers (optional) – Name server IP (DSN) address for resolving host
names to IP address and vice versa.
Applicable when GPRS parameter “DNS servers” is set to “User defined”.

server IPs automatically from GPRS network.
