hey,
But why did the TLS Hello has a TTL lower that the TCP Syn ?Do you have any information on that ?
Consumer CPEs are typically some BCM reference design where initial TCP handshake is handled by linux kernel and everything following (including NAT) is handled in SOC.
I've seen those systems not decrement TTL at all, decrement TTL before checking if packet is destined to itself etc. This case is weird as typically the hardware part is faulty, not the kernel.
