Frequently Asked Questions and Technical Support
Security for the Raven
For specific information about the security of Cingular’s network, contact your cellular dealer
directly.
The IP addresses configured need to be appropriate for y
our network. For most internal networks,
using the IP range of 192.168.x.x is generally preferred. The first three parts (called octets) need
to be the same for all devices on the network (such as 192.168.1.x), but you can use any number
from 0 to 254 for the last part if you use a subnet mask of 255.255.255.0 (fewer numbers are
usable with different subnets). The last part for each IP address on the network needs to be differ-
ent.
The *HOSTPRIVIP and the *HOSTPEERIP need to exist on same subnet, the easiest subnet to
configu
r
e is 255.255.255.0 which allows for 255 IP addresses on the same subnet. Unless you
understand the complexities of subnetting or you are instructed to use a different subnet by your
Network Administrator, it is safe to use 255.255.255.0 with an internal 192.168.x.x network.
Unless you are instructed to use a dif
f
erent IP range and subnet by your Network Administrator,
using the 192.168.1.x or 192.168.0.x range with a subnet mask of 255.255.255.0 is recommended.
Caution: If the IP address of the device or computer connected to the modem is dif-
ferent from the one configured in the modem as the *HOSTPEERIP, communica-
tions will fail. If the Subnet Mask is configured diff
erently in the modem than on
the computer or device to which it is connected, you may not be able to communi-
cate between them.
Does EDGE/GPRS provide any security?
While the structure of the EDGE/GPRS network provides data security, it is still recommended
you use a VPN for additional data communication security.
If I change the password in my Raven and forget it later, can I still access the
modem?
If you changed your password from the default, you can have your password reset by calling or
emailing AirLink’s technical support.
The support technician will ask you for a Challenge Co
de whi
ch you can obtain using Wireless
Ace. You will be asked to send this information in an email to [e-mail] along with
your name and company. Password resets are tracked.
