Setting up Synology NAS for external access

[Snailtones]

I'm having issues setting up an EE Smart Hub (the newer white router came after the Bright Box 2) in DSM 6 on a Synology NAS? I'm getting an issue when setting up router with it not getting past network environment check (on the NAS) saying that there are two or more routers on the network and then that no UPnP is found though I've set the router to have UPnP on. It suggests setting the router to Bridge Mode but I can't find anywhere that I can do that with this router (I don't think that's possible) and the router isn't listed on the next page on the NAS for manual setup.

I think if I can get past the issue of the NAS not wanting two routers on the network then UPnP should be able to sort the rest. I do have a network booster on the network which has a different SSID but is connected to the EE Smart Hub to extend range. I can't do without this as it is the only way to maintain access to my solar set up as the range is too far for the SH. I appreciate this is query is mostly about Synology but figure that it's quite a popular brand and that there might have been some other people using the Smart Hub and a Synology NAS who have some shared experience.

Thanks for reading.

Which router do you have? The Smart Hub is black. Read off its label or top of its admin pages.

Which EE BB product have you bought?

No EE router can be put into modem-only/bridge mode.

Sorry, that should have been 'Smart Router'. It's basically a white oblong with nothing on the front but EE and a circle of light on the front (which I turned off as it was pretty annoying where I have it!). I can't find more about the model as it all just seems to be passwords etc

What does it say after you log into the router on the Advanced Settings / Broadband / Internet page? Obscure your names & any numbers in the BB Username but post the 1st 2 parts of the IP addy.

Is this what you mean? The last numbers on all the bottome TCP/IP stuff are all different but wasn't sure if it's best to blank those posting here

[edit] not sure if that picture is uploading. Hopefully this link will work https://photos.app.goo.gl/fzvWiwGjs2NAKnuW8

Don't worry, your images were awaiting approval. I have now done so & they should appear soon.

Is that all of it? Is there a WAN Port setting at the foot?

I ask again what EE BB product do you have?

[Snailtones]

That's everything. There isn't anything under that (it's the bottom of the page). There aren't any WAN port settings on that page and I don't have anything plugged into the WAN port. Sorry, I missed what you meant about the BB package. I'm on a home package which is 100mbps

[Snailtones]

Just noticed that the data rate says 1000Mbps so I guess that's the BB Package? I guess that's probably the Fibre Plus plan as FIbre Max 100 should be higher than that

[Snailtones]

Curious as to how the BB package would make a difference to the router settings? SUrely that's just either home or business and then the speed? I haven't got anything like static IP set up but wouldn't have thought that would be making a difference at this stage anyway?
