I bet the phone is not pointing to the SG-3100 to resolve all DNS request when using WIFI.

A few people have posted here with very similar problems, usually involving Samsung. I can't speak for them, but my pfSense (Supermicro X11SDV-4C-TP8F) is configured as the DNS server and works well with Android Pixel phones, but not Samsung.

My point was that a default router configuration, even if it receives an external IPv6, still does not prefix-delegate a globally-routable address for use by LAN devices. I'm sure you're aware pfSense does not enable this by default, so your average consumer router doesn't either. I just did this recently so the experience is still fresh in my mind. IPv6 on the LAN, not device-generated link-local addresses, is a deliberate configuration in pfSense, not the default.

With my ISP, if you use their modem in gateway mode, it will provide IPv6 as well as IPv4. The problem arises when people install their own router. Since they're not aware of IPv6, they likely won't configure for it. I haven't used one of those consumer grade routers on my network for several years. However, 10 years ago, my firewall was built on openSUSE Linux and I only got IPv6 by running a tunnel. When my ISP started providing IPv6, 4 years ago, I switched to pfSense because my old firewall wouldn't handle DHCP-v6-PD. I also suspect many who should know better don't enable IPv6 because they're not competent with it.

If Wifi calling uses a publicly available DNS or even one internal to the carrier, that shouldn't be an issue. Also, I did a host lookup on the address used for Wifi calling and it didn't return a host name, so it may be configured by actual IP address, rather than host name.

Guilty...my ISP gives both; yet, because my brain goes into foreign mode and refuses the hexadecimal, I stick to IPv4...silly! Need to overcome it soon!

But your Samsung phone works with wifi calling and SMS, like most people.

Well, I am an Apple person...so iPhone here.

There's no time like the present. PfSense works well with IPv6. As for hex addresses you just don't think of them. As there's no configuration involved, everything just works.

That's OK. We all have our faults.

What are you doing in a pfSense forum, shouldn't you have an Air-something-or-other routing your network?

Ah...I had been thinking to slowly implement on LAN...you might change my mind.

Network consists of pfSense, Mikrotik, Netgear managed switch, and two Apple Extremes...likes all!

I have Verizon for cell and had the same issue with the latest Android version. Text messages would hang, or not go out at all.

Turning off IPV6 on my internal LAN connection, no issues.
I can now text without issue.

Wife's iPhone (X) didnt seem to be affected.

Your post would be more informative if you included the Android phone make and model.

Then there's a problem with the phone. Call Verizon support, to see if they know anything about this.

There is a problem with the phone, as I thought had been demonstrated by all the Samsung Android phone complaints in this post. But Verizon doesn't control the phone OS, they can't do a thing. Try calling Samsung? Yeah, good luck with that. The only practical answer is to ditch Samsung phones if you have an IPv6 home network.

I had no issues with the Ubiquiti edge router I ran for the last year+.
The phone is an S10+ running the latest Android (updated 5-6 weeks ago to update 11, has not gotten update 12 yet)

I installed a new pfSense device (basic install) and now have the texting issue.
Setting ipv6 to none on the LAN interface fixed it (google led me here to this post)

I'm not saying it's Samsung, android or pfSense simply that it started with the install of pfSense, and this fixed it.
It could very well be a security update or setting specific to the phone, but it appears I'm not alone in this issue.

Now when I get time I will put the edge router back in, and enable IPV6 on its internal LAN network and see if it happens.

It appears the only complaints in this thread are Samsung Android, all my Android Pixels are fine with pfSense IPv6. While that may not be definitive proof, it is enough for me to toss the Samsung phone. I'm not wasting any more time looking at Samsung's problems.

It seems that it would be more practical to just disable ipv6 on the wireless network if you are using wifi calling. Try turning it on again when you get a new phone. Doesn't seem very practical to buy a new phone when you could make a simple configuration change that will fix the issue. Unless you just want an excuse to buy a new phone.

You're entitled to your opinion. But on MY network, which I just went through considerable time and expense to upgrade, I choose to abandon the bugged device rather than compromise network functionality.
