Chapter 6 Network
Obtain DNS Configuration from WAN Connection
STEP 1
STEP 2
STEP 3
From the LSM menu, select Network > DNS.
On the DNS page, select Use DNS configuration from WAN connection.
When this option is selected, the DNS server configuration returned from the ISP will be used. Alternatively, the DNS servers can be explicitly set using the manual configuration option.
Click Apply.
Note If you have enabled and configured the DHCP server option for the device, you can override the DNS settings returned to DHCP clients if necessary. For details, see “Configure DHCP Server” on page 169. If you do not override these settings, DHCP clients will receive the DNS server settings used by the device itself.
Default Gateway
If you have configured the External Interface to use a static IP address, then you must manually configure the default gateway. The device uses the default IP gateway to route packets when it has no other route to a given IP address.
Note If you are using L2TP, PPTP, PPPoE, or DHCP, then the default route will be automatically configured by your ISP and you cannot configure it yourself.
Configure the Default Route
STEP 1
STEP 2
Go to Network > Configuration > Default Gateway.
On the Default Gateway page in the Manually configure Default Gateway field, type the IP Address for the default gateway.
Enter the IP address of the next router on the WAN side of the device into the Default Gateway field. Your ISP will provide you with this information.
