Still working?

Is this challenge still working? I wrote a python script that gets refreshed port number and immediately connects to that port from local port 42 but I always get a "connection refused" message. If I am not wrong there is a 5 second timeout but script runs in less than 5 secs. Please help, thanks..

Thank you. Do we have to connect from public ISP given IP or can we connect from local network?

I use curl local port option, python socket bind, etc. I even see local port as 42 in Wireshark but solution is not accepted.. please some hint.

WeChall has to see the port as 42, so yes, the "from public ISP given IP".

Hımmm thanks a lot so it is impossible to solve it because our ISP uses NAT and I don't have a publicly accessable IP address 
( I spent nearly a week of time to solve

I think nat will keep your source port...

When I look inside the ADSL modem, it says my public IP is 100.113.191.169 but when I use web sites such as whatismyip.com, etc ,, my IP seems like 78.190.10xxxx.xxxxxx . I think ISP has a shortage of IP addresses . Also it is interesting that many people share this 78.190.xx.xxx IP address, so if there happens a legal issue, how will the authorities know which person did evil things?

I bet the ISP keeps logs of every connection, also NAT states.
