This is a guide to relay a hotspot via Relayd with TTL/HL modifications. This works well if it's the only option, but the use of relayd can introduce bottlenecks if the network is too fast for the router's cpu. Setting up a bridge with DD-WRT or Tomato does not have this issue, but ymmv depending on ...

I slapped together a test app that's meant to allow rooted users to control their ipv4 address/subnet while tethering/hotspotting. If it works or not for your device, I'd appreciate any feedback.

If your using PDAnet, or any other proxy, packet TTL is set to the correct value when recreated on the phone. You'd need root to disable the tether provisioning, then APN and TTL modification would be something to consider.

I'm stuck on this part of the guide for creating the bridge...I don't see a "Devices Tab"

Sorry I didn't catch this. On previous OpenWRT, instead of
Under Devices -> br-lan click 'Configure...'
Under the General device options tab
Add 'eth1' to Bridge ports
you'd add the interface here ...

Modify TTL/HL for Bridged Traffic Using Traffic Control

* Don't use this , use the method above. This is here just to document an alternative method.

opkg install tc

This is a guide for bridging your phone/modem's tether to an OpenWrt (21.02) router. This lets you connect clients through the router's wifi and ethernet, supports ipv4 and ipv6, and includes working rules to modify the TTL/HL of your traffic. On networks that do not use cgnat for ipv6, like T ...

You would setup two LANs with unique subnets. Bridge each LAN to it's own wireless interface. You'd have two masquerade rules in your nat table for ipv4 and rules in the filter table to allow bidirectional traffic for both LAN<->WAN pairs. Then add routes for both LANs pointing to the appropriate ...

I used TPWS for anti-DPI:

It's easy to build it for different platforms like routers and Android, so you can set it up however you like.

I don't have Vizable, but it's not surprising their out proxies are that bad. Cellular is kind of a mess. It's possible messing with the APN protocol might help. Setting IPv4/IPv4v6 or IPv6 can change how xlat is set up and work around weird issues if your device and provider support it. That's the ...

AT&T Wireless is using a NAT for both IPv4 and IPv6. T-Mobile is using a NAT for IPv4 and IPv6 is given a full open connection. I think Verizon is the same as T-Mobile.

You won't be able to accept incoming connections through AT&T through any consumer plan without forwarding from a remote server ...

This is something better solved in software, if you have root/are jailbroken.

The information here is from my own research and experiments. If you know better, please do share.
The standard way to classify hotspot/tether traffic on mobile networks is through the the APN settings. Android phones will set this through a hidden dun APN entry, while modems will only have metered ...
