Well I do know a bit about networking, but not so much as how to do this. Since the laptop is shutdown every night, it's IP is changed every time I connect w/ a different pc first. This is annoying especially when I must have certain ports open for certain computers. The only solution I see is opening the same port for the IP's 192.168.1.40~47, but this isn't practical when I have to make changes. So how do I assign an IP permanently to a laptop on my network?
