I am trying to create a peer-to-peer python app using the socket library. I am curious to know if there is any way in which I can use the socket library to connect to another computer outside my local network without any manual steps like opening ports on the router for port forwarding. Do I need to use an already open port on the router (given that routers have some ports open on default)? Please guide me. I am new to socket and networking.
My code till now:-
client-1 (sender)
import socket
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((MYPUBLICIP, 433))
s.send(b"HELLO!")
s.close()
client 2 (receiver)
import socket
with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:
s.bind((MYPRIVATEIP, 433))
s.listen()
conn, addr = s.accept()
with conn:
print(f"[CONNECTION_ALERT] Received connection request from {addr}.")
while True:
data = conn.recv(1026).decode('utf-8')
if not data:
break
print(data)
The error I am getting:
ConnectionRefusedError: [WinError 10061] No connection could be made because the target machine actively refused it
If needed, my python version is 10
