Question Port forwarding seems to be set up correctly, but port is still closed.

[icarter]

I have port-forwarded before, and as far as I can tell, I have it set up correctly. However when I use https://portforward.com 's port checking utility, it is closed. My ip address is static, and I set a new inbound rule in my computer's firewall, but I see no difference. My router is an eero Pro 6, and I am using an unmanaged ethernet switch. Any help would be greatly appreciated! (My router's firmware is up-to-date)

I can see the external ip of the other device. There are 3 different lines, 2/3 of them are black with a red font.

If it looks like the port is correct, then you need to check your game server to see if there is anything in the log about a connection.
You could post some screen shots of Wireshark -- wipe the first couple sets of digits from the external IP addresses....

There is nothing in my logs about an incoming connection.
Here is a ss of my WireShark:

This acts like the program is not actually active on that port. This is extremely basic stuff at this point so if the port is actually active it will respond with a ACK packet.

Be very sure that the program is active on that port. If it is check the firewall to ensure it is not blocking it. Wireshark intercepts data before the firewall.

The program is running, and I have created both in-bound and out-bound firewall rules allowing the connection.

Disable the host firewall and test. I think you have something wrong there.

My other device can fully connect while my host firewall is off.

 

[icarter]

Do you need me to test anything else?

 

[icarter]

If I can see the connection attempt through wireshark, but the other device cannot connect, does that mean the problem is the windows firewall on my host system?

What do you mean you can see the connection attempt.

You should see a SYN packet come in from the outside machine. The internal machine should respond with a SYN ACK. You will see other packets after that but those are always the first 2.

 

[icarter]

Hey, I don't really know what the packets mean, but that is what I see. Do you have any idea what might be causing the problem?

 

[bill001g]

Maybe see if you can post the part of the wireshark you say "you see the contention attempt"

What you should see is a packet with a SOURCE ip address someplace on the internet send a SYN packet to your PC on using the port you have open.
