JamesFrisch, FraLem, I'm streaming things like Netflix, Prime, Apple TV, etc.

With single NAT, connected directly to the ISP modem WiFi it works without issue.

Double NAT, with OPNsense connected to the ISP modem is where I have issues.

However, JamesFrisch, after reading what you wrote about WiFi, I put the TV on a 5G network (it was on a 2.4G network I had set aside for IOT) and the problem seems to be gone.

I streamed a few different services for a few hours yesterday and didn't have an issue.

I'll keep testing because it seems like every time I change something it works for a while.

But I think you're right. The WiFi is the problem.

I still plan to put the modem in bridge mode eventually.

Thank you for helping me see outside of my tunnel vision!

OPNsense seems not to have been the problem after all. 🤦‍♂️

JamesFrisch, thank you for your reply.

I'm going to read through the link you sent later today and see if it helps.

I have suspected the WiFi. I hope that's the issue. Because I'm out of ideas with OPNsense.

maclinuxfree, I haven't tried that. I'll try it if troubleshooting the WiFi doesn't help. Thanks!

FraLem, I don't know what kind of traffic it is.

I'm having constant streaming issues when I connect my smart TV through my OPNsense router.

It always eventually shows an error saying there was a problem with the stream. Or that there's no Internet connection. It doesn't buffer. It stops completely.

It's not a bandwidth issue. The TV streams flawlessly when I bypass my home network and connect it directly to the ISP modem WiFi.

The other devices on my network (WiFi and LAN, all going through OPNsense) have no connectivity issues. It's just this one TV.

Here's how it's connected:

ISP Modem -> OPNsense Router -> TP-Link AP => smart TV (on a VLAN)

-> = Physical cable connection
=> = WiFi connection

There are no bottlenecks in my network. OPNsense is running on a fast, dedicated PC with plenty of RAM.

I've tried:
- Going through the logs and eliminating all errors
- Allowing all traffic to and from the smart TV
- Using the ISP DNS servers
- Using a static IP for the WAN instead of DHCP
- Setting up pipes, queues, and rules using FQ-CoDel

Nothing has helped.

I've also done lots of packet captures. And there are lots of [TCP Retransmission], [TCP Out-Of-Order], and [RST] packets being sent before streaming fails.

So something is definitely going wrong with the connection. I just don't know how to tell what it is.

The only ideas I have left are to put the ISP modem into bridge mode to eliminate double NAT on the OPNsense network...

And that maybe the issue has something to do with the smart TV being on a VLAN.

Thoughts? How would you troubleshoot this?

Thanks!
