What is MER?
MER (MAC Encapsulated Routing) allows your router to perform routing on the LAN
side and bridging on the WAN side. MER is needed only when your Network Service
Provider doesn’t support IP routing. MER adds NAT functionality, thereby providing
greater security and more IP addresses for your LAN than what is provided by your
NSP.
Why can’t I get a response after entering a URL in my browser?
If you do not get a response, try pinging the IP address. If you get a response to ping-
ing, then your Domain Name Service (DNS) is probably failing. You should contact
your NSP for DNS assistance. If you do not get a response, then try pinging the WAN
Gateway address (of your NSP) to confirm that your router can connect with the NSP.
If pinging fails, check the router’s lights. The WAN lights on the router front should be
green. Also check your cable connections. If everything appears correct, check your IP
configuration and ensure that the gateway and LAN IP addresses match.
How can I connect my modem for dial backup if the connector on my dialup
modem doesn’t match the console port on the router?

Efficient Networks web site at the following address: http://www.efficient.com
My modem is not a V.90. Can I use it for dial backup?
Yes, you can use a non-V.90 modem with your router for dial backup. Be sure to use
the correct initialization string for your modem (consult your modem documentation).
