Hi

I am looking to forward one of my ports through TCP on IPv4. I have connected to the vpn (tried both udp and tvp ports . Then setup Port Forwarding on the ports section. (BEWARE: My ISP has CGNAT so there's double a NAT that I have to punch through)

Before connecting NetStat output is:

After connecting to vpn output of netstat is:

However Port Forwarding over tcp does not work ?

Hello @jelegend

"Connection refused" usually implies that the packets reached your node and were actively refused. A firewall, or maybe the final service, might have dropped them. If you had had the packets lost between the server and you, or not forwarded at all, you would have seen "Connection timeout" error.

Kind regards

My windows firewall is off so I know that's not the issue. My ISP is shitty so maybe they are behind it or I don't know. I thought a VPN might help get beyond any shitty practices that my ISP might be doing.

So is there any way to know what this service etc might be that's refusing it ?  I am not very well verse in the current tech that might be involved in this packet obstruction process Edited ... by jelegend

Hello!

About remote port forwarding you though right. Your ISP can't interfere because the data stream is still encrypted in the ISP devices, up to your own node.

Strange question... It's the software that must receive the packets, in other words the software you run in your system which must be reachable from the Internet, the only software you forwarded an inbound port for.

Kind regards
