hi mike, i was just reading up on some of your recent questions (i got best answer on one of them, which looks similar to this question).



z's answer is technically accurate, but it's not crystal clear what your question is.



if you want to know how to force your isp to give you a different [wan] ip address while you are using your linksys router, you need to change the media access control (mac) address on your router's wan interface. i've found some links that should help you, see below.



the mac address is how most dhcp servers are configured to distinguish different hosts.



if you want a different wan ip address, change the router's wan mac address, then power cycled your router and your cable modem. it may take several minutes to get a new ip address, but it shouldn't take more than 10 minutes.



my old isp used to require mac address registration. they no longer do. your isp probably does not, or else you never would have gotten an ip address when you hooked up different computers (with different mac addresses) to the cable modem. still, if you don't get an ip address within 10 minutes of changing the router's wan mac address (and power cycling the modem and the router), you may need to call your isp and give them the new wan mac address.



p.s. i would have answered your limewire question as follows if it were still open: as far as limewire packets coming in 20 minutes after you've closed limewire, this is perfectly normal, nothing to worry about. even if your firewall is allowing the packets, you have no application listening on that port (can be confirmed with netstat -an), so little or no security vulnerability.Change ip address on linksys?
not sure exactly what your question is but..



your ISP will assign you 1 IP such as the 2 you mentined above. When you plug your router in to your modem, your router will get that assigned IP. Then your router will do NAT (network address translation) and your PCs will get assigned a private IP such as 192.168.1.2 and so on. All those private IPs will gate translated to your 1 public IP assigned to your router. This is how you get multiple systems online with 1 connection / IP
