I have never in my life been unable to connect to a server i bound to 127.0.0.1 or localhost.

Weird. Maybe you have a route of some sort to 127.0.0.1 (which sounds like a security risk). If I run

Code: Select all

nc.openbsd -l 127.0.0.1 7766
on one computer and try to connect from another with

Code: Select all

nc.openbsd -v <ip> 7766
it doesn't connect. However if I use this in the first machine instead:

Code: Select all

nc.openbsd -l 0.0.0.0 7766
it connects perfectly.

Edit: See also https://stackoverflow.com/questions/240 ... t#24057311

Edit2: In https://security.stackexchange.com/ques ... onnections it says that for IPv6 the situation may be different, in that it might be possible to send spoofed IP packets to ::1.

my ipv4 adress suddenly changed itself, i ran ipconfig command and it was definitely changed.

it was

Ethernet adapter Ethernet:
IPv4 Address. . . . . . . . . . . : 192.168.100.7(Preferred)

to

Ethernet adapter Ethernet:
IPv4 Address. . . . . . . . . . . : 192.168.100.3(Preferred)

i created server on that ip and everything can connect through LAN smoothly, that's all I care about. Thanks for all the help!

the ip of 127.0.0.1 is the same as localhost, I'm not planning to use a localhost server, I want to connect multiple devices together.
Yes, but you should be creating host at the local address (localhost) and only then use the local 192.168.x.x (or WAN external) address from the other devices.
a localhost can only be created and connected through the same machine, other devices wont connect to a localhost, that's why it is called localhost. I want other devices to connect, not only mine
As Karai mentioned before, other devices (guests) don't care about your localhost, they would use the external address accessing your server (host).
