revraz Posted August 27, 2008 Share Posted August 27, 2008 Not sure if you can with PHP since the webpage will see what Internet IP they are coming from, not NAT IP.

revraz Posted August 27, 2008 Share Posted August 27, 2008 Do you not want two people from the same IP connecting? If that is your goal, then you need to check if username A and username B is on the same IP.

Indoinme Posted August 27, 2008 Author Share Posted August 27, 2008 No, I want to check if user didn't connect from the same computer. If I just check the IP, then i can't detect multiple user coming from NAT Router with same public IP. how can I check it ? like right now. I connect behind NAT, through ISP Public IP. how can this web tell the different if I connect from other computer the same time ? (my private IP 192.168.0.1, while my other computer IP is 192.168.0.2 connect throught the same public IP provide by ISP.)

revraz Posted August 27, 2008 Share Posted August 27, 2008 Unique usernames and IP combined. Other than that, you can't tell what PC they are on unless you write and check a cookie, which they can always delete. Could also check the Session ID, that will change if they open a new browser.

discomatt Posted August 27, 2008 Share Posted August 27, 2008 Impossible. If your router is broadcasting your internal IPs, throw it in the garbage. Sadly, it's impossible to 100% verify it's the same computer over HTTP. Cookies, even MAC addresses can easily be cloned.
