Ubuntu Server using same IPV4 as my computer?
I think the picture below pretty much explains all of my concern. The page in the picture is of ipchicken.com on my own computer. Below that is a SSH window to the Linux server inside of my house, that has the same IP as my computer. What the heck is happening and will this affect any sort of servers on the Linux box?
The Linux server is connected to the router via Ethernet and my PC is connected via a wireless adapter. Ubuntu 12.04.4 LTS 64bit http://puu.sh/6FLEB.png |
This is happening because both computers, PC and server, are connected to a router which is doing network address translation.

Main PC: Not forwarded Server: Forwarded In technicality will the packets still only be sent to the server since it only has the ports forwarded and will connections sometimes be tried and sent to my own PC? Also, is there a way to turn NAT off? I'm on a NETGEAR WNDR3400v |
Your router will send packets sent to your public IP address to your server for those ports which it is configured to do so. You could even have a configuration where some ports are forwarded to your server and others to other machines on your network. Your router takes care of all of this for you.
Whether you can turn this off depends on what kind of Internet service that you have. In general, having multiple publicly-routable IPs requires a miore expensive business Internet service/ |
