Forwarding networking data through proxied traffic

Hello!

It would be nice for an option to forward networking information (such as MTU), because when having a DNS request that’s proxied, the request comes from Cloudflare itself, which makes getting such information impossible.

I’ve looked and used this tool: https://github.com/ValdikSS/p0f-mtu, but since requests come through Cloudflare, there is practically no use for it.

Thank you.
