I wrote a basic server-client scripts using sockets, and everything works fine on my LAN, but it doesnt work when im trying to connect to the client thats not in my LAN. I also port forwarded these ports
this is server
###SERVER####
def ChatConnection():
print('Waiting for a connection...\n')
SOCKET = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
SOCKET.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
HOST = ''
PORT = 8989
SOCKET.bind((HOST, PORT))
SOCKET.listen(1)
CONN, ADDR = SOCKET.accept()
print('You can now chat')
while True:
MSG = str(input('\n[YOU]> '))
while not MSG: MSG = str(input('\n[YOU]> '))
CONN.send(MSG.encode())
print('\nAwaiting reply...')
REPLY = CONN.recv(4096).decode()
CONN.close()
this is client
###CLIENT###
def ChatConnection():
print('Waiting for a connection...\n')
while True:
try:
HOST = SERVER EXTERNAL IP
PORT = 8989
SOCKET = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
SOCKET.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
SOCKET.connect((HOST, PORT))
print('You can now chat with server')
print('\nWaiting for server...')
while True:
REPLY = SOCKET.recv(4096)
print('\n[USER]> %s'%REPLY.decode())
MSG = str(input('\n[YOU]> '))
while not MSG: MSG = str(input('\n[YOU]> '))
SOCKET.send(MSG.encode())
print('\nAwaiting reply...')
SOCKET.close()
except Exception: pass
what i need to do so this will work on the WAN?
