I'm confused over this IP business!
If I connect directly to the ISP box, I get one IP; if I connect to the router, I get another, and this one seems to be the valid one, as I can use it in, say, Google analytics to exclude my own visits.
If that is the case, can I use the router to set a PERMANENT IP?
My router is a Netgear WGR 614 v7
Thanks for your question qim.
The difference you are seeing is the difference between the IP assigned by your ISP which is your "External IP" and the "Internal IP" which is assigned by your router to allow multiple users to access the Internet through your single External IP using a protocol called NAT(Network Address Translation).
You can get more detail here.
