Tried everything, IPv6 still goes off :/

@joezeppy
Thank you for your feedback! I am not alone in this. Might try that!

@sja1440

Why do you set "Request only an IPv6 prefix Checked "?  Is that required by your ISP?  Do you know what mechanism is used to get the ipv6 address of the gateway?

I followed this guide, the only one I found of a user in the same ISP as mine, PFSense instead
https://forum.meo.pt/internet-fixa-e-movel-11/pfsense-ipv6-155245

Unfortunately I dont know the ISP mechanism really for anything. Completely ignorant to this matter

It would be good to know if your delegated ipv6 prefix is static or not. Maybe, try comparing it over a few days with a few WAN restarts in between?

Made a forced ISP Modem restart, IPv6 is back, without touching the OPNsense Router. The only difference when comparing IPv4 e IPv6 I noted was the IPv6 Address as
"Dynamic IPv6 prefix received"

When your ipv6 connectivity is functioning, could you share the first 8 hex digits of your WAN ipv6 address (no more than 8 since otherwise it might identify you). You can find it on the OPNsense Da.shboard

This?

Will check your suggestions! THanks!

@Ben S

No Ben, I will try that too! Thank you

Already have all my VLANS using this, Router Advertisements set to Unmanaged to all. Unfortunately stil lgets the issue

I get my IPv6 address via
DHCPv6, 
Request only an IPv6 prefix Checked, 
Prefix delegation size 56,
Send IPv6 prefix hint   Checked

When I mean it goes out, I mean it fails all internet IPv6 tests, only IPv4 stills online.

I am not sure if its static or dynamic IPv6. I have to keep looking for change to confirm?

2) When you say that "ipv6 goes out". What do you mean? For example, when "ipv6 goes out":
does your WAN still have an ipv6 address (look in the Dashboard under interfaces panel)?
does your LAN still have an ipv6 address? (as above)
does your PC still have an ipv6 address?

Yes WAN still shows an ipv6 address.
I run a LAGG, with VLANs, and all individual VLANs have their IPv6 addresses.
Yes my PC shows an IPv6 Address

(3) How do you get your ipv6 prefix from your ISP?  That is, how have you configured the WAN interface for ipv6

Mentioned above

(4) How do you assign ipv6 prefixes to your devices on the LAN:

Tried both ways, DHCPv6, and now using SLAACK only

(5) Have you configured the LAN interface to use "Track Interface" as the ipv6 configuration type?

Yes they are

(6) I assume that ipv6 connectivity comes back when you reboot your OPNsense device. Correct?

That is correct, it does come back when I do so.

Hello all,

My OPNSense Build has been configured to my liking, following several tutorials online. But this one thing is making me having to consider going back to my ISP Router if I dont find a solution fast enough.

The IPv6 just goes out, without notice, not sure how long it takes, but i would say about 12 hours of flawless operation, then bang, i do an IPv6 Test and its out. I have seen several topics with similar problems online from years ago.

I tried already the most hardcore solution that a user has mentioned did the work for him, reinstalling it all from scratch. I did just that yesterday, and woke up this morning to find my IPv6 offline again.

I really don't know what else I could do. I humbly ask for help, the entire home network gets affected when this happens, i just cant keep OPNsense if this isnt solved fast enough.

Diagnostics, things to try, I am all ears!

THank you all

Found the issue Patrick,

It was IPv6, which made my cellphones have issues with these apps. I saw this post and decided to try, IPv4 only and its back on!

https://forum.opnsense.org/index.php?topic=32674.0

Now i have to investigate why that is happening here!

After spending hours on this, I am thinking there may be a Firewall Rule blocking out these Music Streaming Apps?

Spotify doesnt work, Prime Music doesnt work. Should I enable specially rules for specific Apps I Want in OPNSense?

Thank you for the help Patrick,

My network is my ISP Router as Bridge. That goes into my OPNSense Machine. Then goes to a MikroTik Switch, from that a cable to my TPLink Deco AP, which is set as Access Point, DHCP turned off. The TV Box is not connected to the Switch, it is still connected to the ISP Modem.

Nothing fancy enabled, I just followed the basic tutorial, enabled DHCP only on OPNSense, no Firewall, All allowed. Tried both ISP DNS, and Custom DNS, no difference.

I read that my IPTV TV Box might be flooding my network due to me not doing VLANs, or other Multicast stuff I really dont know how to do. But I am not sure if this would be the reason of my Wifi devices misbehaving.

What I noticed since we switched to OPNSense, is that Twitter App stopped loading the images, and the videos, when both my wife and my Phones are connected to the Wifi. Spotify just doesnt work at all, loads as Offline Mode.

And whenever I try playing a music at Spotify Android App, a new Log shows on like that entry on my Unbound DNS log.

I confirmed the Mac Address is from my TV Box, which is actually IPTV.

I wonder how that could be getting in the way of my Cellphones Wifi?

So the "NODE_WIFI_ec:a9:40:29:be:f5" hostname is your TP-Link device or your Spotify client/server/whatever?

This is what is shown to me in the OPNSense ARP Table

192.168.50.111   ec:a9:40:29:be:f5   ARRIS Group, Inc.   igc1   lan   NODE_WIFI_ec:a9:40:29:be:f5

What is weird is that that Arris made my TV Box? THe ISP is Fiber going from the OTN to the ISP Router, then a Lan going from the ISP Router to the TV Box. And the ISP Router is Bridge mode going to OPNSense

Hi! Thank you for your reply.

It doesnt seem to be a way to me to control how the TP-Link Deco unit creates its hostnames. Unless I could modify it somehow later down the path?

I find very weird that nobody had this issue so far? The TP-Link Deco is one of the biggest selling Mesh Units available, and to find out it doesn't work properly with OPNSense and there isnt anything that could be done is shocking.

The previous Routers never complained, which is even more strange. I had the ISP one, and an Asus RT-AX86U, both Stock and Merlin Firmware. All worked fine?

I really hope this doesnt leave me with just the option of needing to change my OPNSense to another solution, because i really wanted to make it work in our home, but I cant have all my Wifi devices full of issues.

So, I am getting these log errors whenever I try to access SPotify on my Cellphone via my WiFi AP connected to Opnsense.

"dhcpd leases: NODE_WIFI_ec:a9:40:29:be:f5 not a valid hostname, ignoring"

This is generated by my Deco TP-Link XE75 Node Wifi, where my Phone is connected to.

I read underline might be the problem, but there is nothing I can do to change the Deco device. So how can I tell Unbound to accept this kind of hostname?

Thank you!
