How do I find my IP NAT?
- Go to www.whatismyip.com. If the IP it shows is different from the IP of your NIC, you’re behind a NAT. –
- If by NAT you mean any NAT including a WIFI router for example click the windows button, type cmd, click on command prompt, type in ipconfig and press enter, see what it says to the right of “IPv4 Address”.
Can we ping NAT IP?
Yes. As long as the router allows the Ping request to pass outbound and properly tracks the request so that it can return. Most routers I have dealt with handle this correctly. Pings in though a Firewall (NAT or not) are often blocked.
Can a private IP address be traced?
Are private IP addresses traceable? Yes, private IP addresses are traceable, but only by other devices on your local network. Each device connected to your local network has a private IP address, and each device’s private IP address can be seen only by other devices within that network.
Why can’t I ping my friends IP?
This means that you will not be able to ping your friend’s IP because something on the internet is blocking it. He can ping you because there’s nothing blocking pings originating from his network (that can also include the 4.4. 4.4 device that is blocking your pings).
How can I get my external IP address from behind a NAT?
You can’t get it directly from the machine you are on. You’ll need to get a machine on the internet to tell you. Depending on the type of router you have this might not be possible. If your router speaks snmp you can use that to grep the WAN IP address of the router. If it doesn’t I wouldn’t know how to do it.
How can I obtain the internal IP of a computer?
If you determine the distance to the NAT (say 10 hops) and the actual concealed host is actually 12 hops (or more) away, you could send a SYN to the port-forwarded port on the NAT with a TTL value of 11. If it is simply rewriting the address (rather than acting as a reverse proxy) then the TTL will be unmolested.
Can a firewall connect to a NAT device?
Actually, your plan could work, depending on how the NAT device works. Typically, NAT devices map the internal IP and source port to the destination IP and port so that it only allows that IP and port to communicate back to the internal IP. This makes NAT a very crude and poor stateful firewall.
How are NAT devices connected to the network?
Typically, NAT devices map the internal IP and source port to the destination IP and port so that it only allows that IP and port to communicate back to the internal IP. This makes NAT a very crude and poor stateful firewall.
