Heyas, I've been planning redoing my wired network for a bit now. I am curious if my plan is optimal for my needs. Here goes: The old (current) network is an 8 port hub, with 3 computers and my DSL modem connected. The DSL setup is each computer has a static (internal network IP, given to me by my ISP), and each computer uses the DSL modem's IP as its gateway. Since these 3 computers are on a HUB, it's easy to sniff the packets of any of them, from each other. More specifically, there's 1 Linux box, and 2 Windows XP boxes (the Linux box is the one I prefer to use when sniffing packets). So, enter wireless SWITCH (WRT54GS). As you all know, sniffing a switch is near impossible (ARP poisoning would be a possibility, but I don't know what issues this may cause my network, so for now, I am avoiding this possibility). My solution, is to put the 2 Windows XP machines on the SWITCH, and add a laptop in the near future. Now, in order to still be able to sniff packets, I believe I must do the following: Plug the HUB into the WLAN connection on the SWITCH, and put the Linux box and DSL modem on this HUB. Seems like it would work - I dunno, haven't done this yet. ;-) Now, as for sniffing packets, since I am outside the SWITCH, (and I *think* I will have to use NAT & DHCP on the switch/router), will they all have the same MAC & IP address (the router's MAC & IP)? This isn't a huge issue, I just want to be aware of exactly what I will be dealing with before I make the plunge on this network redesign. Anyway, thanks for reading, if I am incorrect on anything above, or, you can see a more optimal setup - please, let me know. Thanks muchly.
