Hi there

 

I am with Spark, on Fibre Broadband, Using standard SPARK HG659b router. And Synology NAS 415play. 

 

Firmware on router: V100R001C227B022

 

NAS is fully up to date. 

 

I have in the recent past (a few months ago) had no issues connecting to the NAS from outside the LAN on: 

 

port 5001  to access the NAS Diskstation Manager 

 

port 1194 for VPN

 

port (non-standard #) for SFTP

 

I have not changed anything in recent times. But I can no longer access any of the above. 

 

I have checked the port forwarding rules in the router, and they all look good to me. No apparent change. 

 

I have checked the firewall in the NAS, and that also looks good to me. No apparent change. 

 

I restarted both the router and the NAS

 

As far as I can tell, I should be able to connect, but I can't. 

 

[edit] I can connect via the Synology "quickconnect.to/quickconnectID", which I believe uses 80, 443, and/or 8888. 

 

I don't know enough to understand where the block might be happening.  Any ideas how I can work out where the problem might be happening? 

 

Thanks

How are you connecting to the NAS from outside the LAN? If you are simply accessing via the external/public facing WAN IP address from within your LAN then this won't work for this particular router (HG659b default config doesn't come with NAT loopback rule).

I am testing by connecting to my hotspot on my phone which is using cellular network. 

 

I first noticed the problem when I was offsite at my coworking space though.

On the IP address you're posting from the Diskstation is responding with a login page on :5001/HTTPS. I have not tested anything else.

 

I suspect perhaps your coworking space may be blocking other ports apart from the basic HTTP / HTTPS ports on their network.

You’re using a VPN so that should be the only open port. You connect the VPN then access the nas.

Hmm OK. That's really strange. I have been able to test this by using my hotspot in the past. I wonder why I am not seeing the same as you. 

 

Thank you for that info. Very useful.  I did not consider that the coworking space may have changed something.

Yes you're probably right about that being the better way. I was trying to diagnose my VPN connection issues by also looking at a bunch of different ports that I had open at various points.  All with a view to getting my VPN connection working again. 

 

 

 

Thank you

Possibly not a necessary test, but have you tried (if possible) accessing it with the same device from another external network other than your coworking space?  (mobile hotspot, friend's or public WiFi).

Hmmm I think I might have some sort of firewall issue on my own machine. My phone can connect to the VPN no problem, but if I use the phone as a hotspot for my Macbook, I cannot connect. 

 

That narrows things down significantly. I have changed security software recently. Dropped Norton for Avast. I'm betting that's the problem.  I was looking at the wrong machine for the issue. 

 

Thanks for all your help.

Yes, via mobile hotspot.

Sorry missed your part earlier RE using mobile hotspot.  Glad to see you've potentially narrowed it down :)

FYI

 

In general , AVAST is a problem. Its no better than spyware/scareware/bloatware itself .
Get rid of it ASAP .

Yeah - while I was reading up on the potential issue I came across several reports of such things. I actually liked Norton, but I was having big issues with it. It kept blocking my browsers from accessing the internet!  So it had to go. 

 

 

 

I will see if there is a better alternative.

If you're using Windows 10 there isn't a need for any third party antivirus software. The built in protection is all you need and works very well.

 

Save your PC's resources and uninstall it all - ensure Windows Security is enabled and you're done :)

Set a temporary port forward to an internal device at port 80 then see if you can access your.ip:80 from the browser on your phone with wifi off. If not then something is stopping the port forwarding.

Who’s your isp? Orcon for example have an option to block common ports. Something that can turned off in your account settings.
