STEP 4 Set up the SnapGear appliance’s Internet
connection settings
First, attach your SnapGear appliance to your modem device or Internet
connection medium. If necessary, give the modem device some time to
power up.
Select your Internet connection type and click Next.
If connecting using a cable modem, select the appropriate ISP. Choose
Generic cable modem provider if unsure.
If connecting using a regular analog modem, enter the details provided
by your ISP.
If connecting using an ADSL modem, select Auto detect ADSL
connection type and enter the details provided by your ISP. If auto
detection fails and you are unsure of your ADSL connection type,
contact your ISP.
If you have a direct connection to the Internet (e.g. a leased line), enter
the IP settings provided by your ISP.
Note: For detailed help for each of these options, please refer to the
User Manual.
Once the SnapGear appliance’s Internet connection has been set up,
click Next, select Reboot and click Next again.
Note: If you have changed the SnapGear appliance’s LAN connection
settings, it may become uncontactable at this point. The next step
describes how to set up the PCs on your network to access the
SnapGear appliance and the Internet.

STEP 5 Set up the PCs on your LAN to access the
Internet
If you haven’t already, connect your SnapGear appliance’s LAN Ethernet
port directly to your LAN hub using the straight through Ethernet cable
(blue).
To access the Internet, the PCs on your network must all be set up to
use the SnapGear appliance as their default gateway. This can be done
a number of different ways depending on how your LAN is set up.
If your LAN has a DHCP server already, proceed to STEP 5A.
If your LAN does not have a DHCP server, proceed to STEP 5B.
If you are not sure, you probably want STEP 5B.
STEP 5A LAN with a DHCP server
Add a lease to your existing DHCP server to reserve the IP address you
chose in STEP 3 for the SnapGear appliance’s LAN connection.
If you chose to set the SnapGear appliance’s LAN connection settings
using Manual configuration, you may simply remove this address from
the pool of available addresses.
Enter this same IP address as the gateway IP address to be handed out
by the DHCP server.
Enter this same IP address as the DNS server IP address to be handed
out by the DHCP server.
Restart all the PCs on the network (this will reset their gateway and DNS
addresses).
Note: The purpose of restarting the computers is to force them to gain a
new DHCP lease. Alternatively you can use a utility such as ipconfig to
release then renew a lease, or disable and re-enable the network
connection.
STEP 5B LAN with no DHCP server
A DHCP server allows PCs to automatically obtain network settings
when they start up. If your network does not have a DHCP server, you
may either manually set up each PC on your network, or set up the
SnapGear appliance's DHCP server.
