Plusnet Hub 2 - static device issue

JC4 — Thu, 06 Oct 2022 15:34:57 GMT

Any known issues or some weird config on the above?

New Hub2, one of the devices on the LAN is a home automation system on a static IP 192.168.1.55 (outside of the dhcp range), works fine standalone on old BT router and other Billion router.

Patch it into the Hub 2 and cant get any local comms to the home automation system. Can see it fine in the static list and ping it but thats it. Have tried firewall on and off on the Hub.

Almost like its blocked or filtered.

@JC4 does that mean just ping it from the router ? or can you ping it from elsewhere on the local LAN ?

I can ping the home automation (MiniServer 1.55) from other devices patched on the LAN (can’t say I tried it using any router tools directly). Link lights on and all looks normal when I patch it into the Hub2, just can’t connect to it using the specialist automation software on my laptop.

Plug it all back to the old Sky router and its sweet. I’m not 100% sure how the specialist software connects or on what ports but it detects it okay on the Plusnet Hub2 just fails to connect.

At first I thought some kind of MAC address or filtering/firewall was stopping it but scratching my head now.

I need to setup port forwarding for remote access on the Hub2, through to the Home Automation system but if I can’t administer the miniserver system locally then I’m stuck.

@JC4 yes, I thought that, then changed my mind. The fact that ping works confirms that's not a problem.

Plug it all back to the old Sky router and its sweet.

Is the LAN IP address for the Sky router the same as the Hub 2 (192.168.1.254) ? if not, the default gateway will need changing on the Miniserver.

I’m not 100% sure how the specialist software connects or on what ports but it detects it okay on the Plusnet Hub2 just fails to connect.

Its possible that the software communicates via an external server, in which case the Miniserver will need to communicate to the internet, for which it will need the default gateway to be correct for the Hub 2

edit: or you could try changing the LAN IP and subnet of the Hub2 to match the Sky router...

Yes both are pretty much identical (192.168.1.55 for the miniserver), dhcp scope of 1.150 to 1.253 gateway IP 1.254 (left all these out the box for the Hub2 for now). Default gateway on Miniserver checked 1.254.

Same configs work fine on BT Homehub, Billion router, Sky router, just doesnt work via the Plusnet Hub2.

This is the home automation.

I reckon the Loxone admin software detects the miniserver on one port/protocol and maybe sends the login creds on another. Its only the ‘login creds’ that fail when its plugged into the Hub2.

Re: Plusnet Hub 2 - static device issue

The Hub2 shows the Loxone as a static on 1.55 and the correct MAC address.

Very strange.

It shouldnt affect LAN communication but is there a upnp setting on the Hub 2 ?

I'm not using my Hub 2 at the moment so cant check directly but I seem to recall the ability to turn it on & off

The Hub2 shows the Loxone as a static on 1.55 and the correct MAC address.

Sorry, I'm confused now. Surely the Loxone config utility is running on the laptop, the Miniserver has the 1.55 static IP ?

Re: Plusnet Hub 2 - static device issue

Correct yes. Config utility on a laptop (and also a mobile app). The mobile app logs into it fine over LAN on BT and Sky, but again fails when the Plusnet Hub is the router.

I’ll see if I can hunt a upnp setting in case.

I believe UPnP is enabled by default, the setting can be found

Advanced Settings >Firewall >Configuration

@JC4

This is a bit outside my experience, but have you tried giving the problematic device a static IP address within the DHCP range, which I think is 192.168.1.64 to 253 by default?

Just to see if it makes any difference.

Thanks, no not yet (it’s a domestic customers site) so will check on my next visit, I was there doing the external wifi :0)

The Miniserver defaults to 1.77 static if it cant find a dhcp server on the LAN if I am right (was only keeping it static so I could do the port forwarding for remote access). I’ll give that a go though along with the uPNP, will try an address within the range.

Re: Plusnet Hub 2 - static device issue

JC4 — Thu, 06 Oct 2022 17:57:59 GMT

Hold fire, the miniserver was on 1.77 in the Plusnet when I first plugged it up, and I could login, via the Plusnet hub and my laptop.

You maybe right, it only failed when it was set to a static 1.55 outside the dhcp scope! Defo one to prove. Cheers all. I’ll update post once proven. Just in case uPNP sorts it first.

Set it back to dhcp , then set the Hub 2 to fix its ip ( always use same ip ). That way its effectively static but the Hub 2 has assigned it .

@MisterW

Thinking about it now, that is what I had to do when setting up my Netgear ReadyNAS server with a fixed IP address.

Fixing it on the ReadyNAS meant that I couldn't connect to it, so as you say, set the device to DHCP and let the router find it - then fix the IP address.

I never did find out why it didn't work, it doesn't seem to be solely a Netgear problem then so would be interested if anyone can explain why it happens like that.
