We're a bit the opposite here, 2 of us, 2 Internet connections. Might sound overkill, but it's to segregate heavy downloads from everything else. :)
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. 73 de VK3JED / VK3IRL http://vkradio.com
