T-Mobile cellular service on a netgear LM1200 modem no ipv6 gateway

In Packet Capture, filter on DHCPv6, port 546 or 547. Doesn't matter which. If you have an external connection method, such as a data tap, you can connect a computer and run Wireshark. You'll want to capture it during a reboot, so as to get the entire sequence. If you're using Packet Capture, shut down pfsense and disconnect the WAN cable. Then boot up pfsense, start Packet Capture and reconnect the WAN cable.

Here is what wireshark analyzed from packets captured (546 or 547) on the pfsense interface for my cellular modem in bridge mode.

It's better to upload the capture file, as I did above. There's a lot of detail in those captures and you really need to use Wireshark to analyze it.

I have been doing this via a site to site VPN. Since this will involve physical access, I will visit the site next week and try all the above.

When I get a capture file, I'll revist this.

Thanks,

Then I can only assume you didn't reboot pfsense. That's pretty much necessary to get the full sequence. Otherwise, you only get renewals.
