Orbi Port forward random incoming ports

Hi,

 

I configured my orbi to forward port 8123 to a Synology running an instance of a home assistant.

I configured the port and disabled UPnP and opened NAT, but the port is still closed. I tried a couple fo more configurations but the result is the same.

One thing that I notice is that the logs show a random port [LAN access from remote] from like

62.140.132.60:30383 to 192.168.1.17:8123, Sunday, February 10, 2019 15:42:26
[LAN access from remote] from 62.140.132.60:29579 to 192.168.1.17:8123, Sunday, February 10, 2019 15:42:07
[LAN access from remote] from 62.140.132.60:26405 to 192.168.1.17:8123, Sunday, February 10, 2019 15:41:23
[LAN access from remote] from 62.140.132.60:8376 to 192.168.1.17:8123, Sunday, February 10, 2019 15:41:03

 

192.168.1.17 is the synology NAS. 

And I have a router from my ISP running as bridge mode

 

I'm running out of ideas, thank you in advance

Re: Orbi Port forward random incoming ports

Thank you for your replies.

I manage to discover the issue. The port is open, the problem is on my synology. 

My synology is connect with a vpn client, so when its connect I cannot forward the port to it.

Im using this because orbi doesnt support vpn client only server 😞

Re: Orbi Port forward random incoming ports

What do you mean by the port is down? The port forwarding that you did in Orbi seems to be working from the Logs you provided.

The device 62.140.132.60 (which seems to be a device connected to Vodafone NL) is reaching to your Synology port 8123 according to the port forwarding you defined.

The port is closed. So if I connect to the device locally it works. But remotely it doesn’t. What makes me more confuse is that the external port is always a random number instead of the port I configured (same as the internal port)

How do you connect locally? Are you sure that no other ports are needed for this apart from 8123? In this specs I see many other ports being used?

The port you see in the Logs (62.140.132.60:29579) is the source port, the port forwarding that you did in Orbi is for the destination ports, so when device with IP 62.140.132.60 tries to reach port 8123 from WAN it will be forwarded to port 8123 on IP address 192.168.1.17 on LAN and this seems to be working fine.
