We're a bit the opposite here, 2 of us, 2 Internet

Slightly
easier, because you can packet sniff the MAC addresses,
(after eliminating your devices), then setup the static DHCP entries.
Now, you have fixed IP addresses to filter. :) All they have to do
for you to set this up is surf the net. :)
This sounds like a possibility, any
chance of getting the LAN IP
addresses as well ?;
because that's what the E2000 seems to want.
The idea was to be able to fix those LAN IP addresses, if your router
supports what's called static DHCP. How this works is some routers
will let you tell them that if they see a specific MAC address on the
network, assign a specific IP address. Yes, you can sniff their
current LAN IP address, but unless you tie that with a MAC address,
it could change next time you reboot the router.
So, you sniff the traffic on the wireless network, grab the MAC
addresses of the other peoples' gear, then go to your router config
(don't ask me where, this is _totally_ model specific!), where you
setup the DHCP server I guess, and setup the association between
those MAC addresses and the IP addresses.
As for packet sniffing, there is Linux and Windows software you can
use to do this. You should sniff from a machine that's also on the
wireless network. You may not need to do this though, some routers
are able to report what wireless clients are associated with them
(usually in the status or wireless screens). The information from
there is what you need.
Well, that
depends, like everything else discussed, on how far you
want to go. Most routers are not designed to do things this fancy,
I take it that
'things this fancy' amounts to some kind of
packet-sniffing ?;
Packet sniffing is done from another machine, no, I was referring to
what is effectively a form of "guest access" being a relatively
"fancy" function.
assuming the E2000 can't do anything like that;
then it would seem that
short
of building a Linux router; I would have to purchase a fairly
specialised device;
which is usually code for expensive !
so your mileage will definitely vary. Some
routers won't even do
static DHCP, which is a pain when you want to reserve a port forward
for a specific device that moves from network to network.
If you are exploring my
knowledge of data-communications; I can
summarise 'very rudimentary';
I know what an IP- port is, but for the life of me I can't understand,
what is meant by 'forwarding' it !
Bit like the story about the man who turned into an alcoholic;
which was countered by one about a man who turned into a driveway !
Port forwarding is often used when you want to run a server behind
your router. You need to make the server accessible to the outside
world, and that's done by "forwarding" a port on the router's public
IP address to the internal IP and port of your server. Sometimes
this function is called "Virtual server" instead.
