New Connection Troubles

Good Evening All,

First off I just want to say I have dropped the Yayzi support team a message and Liam is looking into it. But in a desperate attempt at saving my evening, I’m hopeful some of you kind people out there may be able to assist.

On Fri’yay’ I got my City Fibre connection hooked up as a new customer to Yayzi.

I was originally on a 154.56.254.XX IP address, which kicked-in in the evening. Throughout the weekend it worked mostly (with the odd drop out here and there).

I emailed the support team and they kindly moved me over to a 217.180.37.XXX address. This came online around 2pm this afternoon, after which time my IPV6 address appeared in the Ubiquiti page. However since I am unable to load all but a couple websites (Youtube and the .Gov site for example). No BBC, not many sites from google etc). My work laptops cannot connect to the VPN etc etc.

I have attached a couple images, in the hope that in my total ignorance of networking I have missed a simple toggle/setting I need to change.

It seems like IPv6 sites are working and IPv4 aren’t? - Is that a thing?

Kind Regards,

PS. please do let me know if you need anything else or if I have left too much detail unredacted :slight_smile:

Firstly Welcome :pray:

Do you know who your works VPN is?
Some sites do simply hate IPv6 but not most.

For the BBC if you go to this url does it say GB?

https://www.bbc.co.uk/userinfo

All looks good to me

What sort of error do you get when you try and access the BBC?

It should use IPV4 by default, Not many places, Support IPv6

Just an fyi.
Prefix delegation size should be 64 not 60

On the LAN side its /64. But the WAN is /60

Works with either 60 or 64 set on the WAN side actually.

Just out of interest are you able to open a command prompt/terminal and ping 8.8.8.8 and see if you get a response?
Then try ping bbc.co.uk
This could well be DNS.
If you aren’t getting a reply on the ping to bbc.co.uk, untick the auto box and set a primary server 1.1.1.1 or 9.9.9.9 or something of your choice.

Good Evening, nice to be here :slight_smile:

The VPN is Citrix

It just loads indefinitely for all websites that don’t load instantly (BBC.co.yk/userinfo included).

I have changed the prefix delegation sizes between 64 and 60 without luck.

I have restarted the UDM Pro Max without luck and have just factory reset (in case I changed some random setting in another page without noticing). When trying to setup the UDM it doesn’t connect to the internet (that includes using the ‘Other Configuration Options’) > DHCP Internet Connection Type> VLAN ID 911 on the 1.1.1.1 DNS Server.

Pinging 8.8.8.8 shows 'Destination Port Unreachable).

Seems like it is an issue on the Yayzi/City Fibre side right? - the UDM is/was picking up IPV4 and IPV6 addresses but the V4 just seems broken. As I say it was working intermittently yesterday and this morning until the IPv4 change.

I have also tried a using a hard reset of the ONT (pin into the bottom), and replacing the ethernet cables without luck.

I’ll hold out for Yayzi to look into it I guess, but at least it doesn’t seem to be on my side.

Thanks so much for all the quick replies guys

Evening.

Are these issues from client devices then? Same or all of them? Can you SSH to the UDM and then try pinging a few sites again, from there? Should then know if it’s an external or internal issue.

Cheers.

So sorry for the delay. Just at work but will try later.

Thanks

I randomly looked on QoS i setup on thinkbroadband for my previous ipv4 address, which is still showing it being ‘pingable’.

Could it be that my DHCPv4 in ubiquiti is picking up the wrong public address?

Trying to see if it would work using the static ip but have no idea what to include for the following:

IPV4 Address: i assume the old one (154.56…)
Subnet Mask: i assume 255.255.255.0
Gateway Ip: not sure but i assume my udms ip (192.168.1.1)

Says ‘Gateway must be inside the same IP range’

Any way to get these details and is it even worth trying?

That gateway IP looks off, where are you seeing this?

The WAN settings page should look like this:
