AdHoc connection issue

Post by itskv » Thu Jun 08, 2023 5:13 pm

1. Whenever I am connecting to server, I am getting this message. But I am pretty sure that I have forwarded port 443,555,1194 and 992 from my VPS server having static IP. What will be the issue? I want clear TCP/IP connection only. UDP acceleration is disabled. Setting "Disable NAT-T" option makes server unreachable by failing the connection retries.

.
2. Server is configured in AdHoc mode as explained in official guide. All clients can get ping reply from server. But when clients try to ping other client, no ping is replied back. Nor they can communicate with each other by any means.


Server is Ubuntu linux and clients are all Windows 10 or 11.

Port 555? Unusual, the ports are not forwarded properly and/or allowed in firewall. Also allow ping in Windows firewall.

Sorry, typo here. It's 5555.
All ports 443,5555,1194 and 992 are forwarded. Firewall allowed. Ping is enabled.

Open a browser and enter https://your-VPS-server-static-IP:5555 - what do you get?

I am not getting any webpage. But I can verify that iptables are allowed and no other firewall is in between.

Again, "the ports are not forwarded properly and/or allowed in firewall".

Look, we're going in circles. If you are unable to do it properly on Ubuntu, ask for Windows VPS.

I tried all possible solution. Nothing worked.

At last, deleted the VPS instance. Launched fresh VPS instance, installed SE again, edited iptables as per need. Then its stared working.

Thank you @solo for the help.
