Orbi Port forwarding (443) Not Working

Hi all,

 

I'm at my witts end in trying to implement a simple port forward on the Orbi. Effectively, I have Home Assistant (HA) running in my network, and have installed a SSL Certificate and implemented a DynDNS Hostname to access the Home Assistant device externally. This generally allows access via https://xxxx.duckdns.org:8123. 8123 being the default Port for HA. I have a portforward for 8123 port calls to be redirected to the server (a RPi) on 8123, and it works fine. According to http://www.canyouseeme.org, port 8123 is open.

 

However, my workplace blocks port calls outside of standard port numbers. So 8123 is blocked, and so I thought I would use Port 443 (the standard SSL port), as the HA connection is using HTTPS (/SSL), and have the Orbi redirect external calls to 443 to port 8123 on the HA/RPi. This should allow me to head to https://xxxx.duckdns.org/ without a problem. The issue is, however, when I set the port forward rule -- it doesn't work. According to http://www.canyouseeme.org, port 443 is closed.

 

Yet, when I do a Port Scan, using a program, on the server from inside the network -- Port 443 and 8123 are both open and fine -- Further, if I access the HA Server internally on https://xxxx.duckdns.org/ it works fine. Now what could be causing it? The only thing I can work out is that it is Orbi which is unable to receive and redirect the port calls from 443, which is why it's closed.

 

Any suggestions on how I could overcome this?

Thanks all!

(p.s. upnp is off)

Re: Orbi Port forwarding (443) Not Working

Some ISPs block port 443, inbound, to prevent people from hosting web servers.

The Orbi could be using port 443. Unfortunately, I don't think there's any easy way to tell short of disabling any features that could be using it, such as remote management, UPnP, etc.

Can you use a different port, like 22 (SSH), instead of 443?

Port forwarding 443 works for me and my apache web server.  So it's not the Orbi, sorry 😞

@TheEther

You're precisely on the money. Turns out it was the ISP which was blocking incoming 443 calls. I've since managed to fix that, and the connection is working smoothly. Thanks for reminding me!
