Actually you can set up a routing table in the BEFSR11(a basic one),
technically the device is both a gateway and a router. Most people will be
using the box as a gateway.

I don't like OT threads and I particularly don't like OT threads about
computers because there are so many misconceptions and misunderstandings
about the technology.
Let's get one thing straight - these little Linksys, D-link, and Netgear
boxes are NOT routers. A real router, like a Cisco unit, has 1 LAN
connection and 2 or more connections (WAN1, WAN2, WAN3 etc) to the internet
or other networks. When it receives a packet from a PC on the LAN side, it
looks at the network address portion of the complete IP address, and then
'decides' which WAN port to ROUTE the packet thru. Its decision making is
based on the # of hops, # of ticks, and other network variables. These
parameters are stored in a Routing Information Protocol (RIP) table.
How many WAN ports does your little 'cable/DSL router' have? One? How can
it possibly ROUTE if it only has one WAN port?!?!?!? When you first set up
your 'cable/DSL router' did you program your routing table? No you did not.
All you probably did was type in your ISPs DNS server address(s), your ISPs
Gateway address, told it to obtain an IP address automatically (from your
ISP), and maybe configured it as a DHCP server for the PCs in your house.
So, one WAN port PLUS no routing table EQUALS not a router. Yes, I know
that's what the box says and that's what the mfr calls it, but it is not a
router - it is a GATEWAY. But even that is not 100% accurate (but it's more
accurate than calling it a router) because the main function of a gateway is
translation between 2 dissimilar networks. IP network and NetBEUI network -
need a gateway. Ethernet network and Token Ring network - need a gateway.
IP network in your house and the internet - need a gateway????? I think
not.
So it's not a router and it's not a gateway, so what is it? It's a box that
uses NAT to provide internet-sharing of the single IP address from your
telco or cableco. That's the main selling point and that's what
99.9999999999999999999999999999999% are being used for.
BTW, I have the Linksys BEFSR11 - 1 WAN port and 1 LAN port which is
connected to a separate 16-port switch.
