After advice given here, but for other reasons too, I got a adsl-router
rather than an adsl-bridge to tigger.
What I've lost is name virtual hosts. My router (dlink 604T) does suitable
virtual hosting, but all the necessary name information is lost before it
gets routed to apache2. ie router:80 -> 192.168.1.254:80
Is there a way of hosting multiple sites with a router?
Your router only forwards to addresses and ports. It knows nothing of the
protocol you're forwarding.
This statement is not only confusing but completely wrong.
Any router knows the IP protocol of the message it is forwarding contrary to the above statement.
Specifically, any router knows IP protocol since the Internet is an IP network.
That's why it knows the IP address of device it is forwarding to. Another way
of saying this is
if a router does not know the protocol of the message it is forwarding then it
will
not be able to establish the ip address of the target device.
This is unlike hubs, bridges, and switches that forward packets of data
using MAC-ADDRESS to determine the target device and have no knowledge of
the ip protocol on the message. Unique MAC-ADDRESS is burned-in to each device.
Routers use IP protocol to ascertain IP address to determine the target device.
And it is a pre-requisite that routers know ip protocol of the message
for it to be a router.
Hubs, bridges, and switches does not need to know IP protocol; routers do.
Routers are layer 3 devices; hubs, bridges, and switches are layer 2 devices.
Hope this corrects the mis-understanding.
