Following numerous guides I set up TTL mangling on my Beryl.

My setup is

M1 (Ethernet)--> (WAN) GLiNet Beryl (LAN) --> (WAN2) USG Pro 4

This is purely for my backup WAN on the USG

All 3 devices are set with DGHCP enabled because it was easier than trying to get bridging and ip passthrough configured and my understanding is that being triple NATd doesn't matter because cell connections are CGNATed anyway.

So what I'm trying to do is test if my TTL mangling was successful. I get the same speed either way and T-Mobile Business doesn't have a good way of indicating if Im using device data or tether data.


There's dozens of guides out there on this process but none of them tell you how to confirm it works other than checking the speed you're getting.

Thanks in advance.

I'm curious as to what the purpose of the GL.iNet router is? If it's just for TTL mangling, you can do that directly on the M1.
