A fun project disassembling and understanding a Vodafone TG3442DE cable router (aka Arris Touchstone TG3442: commscope.com product page).
- Using the cable-interface for wiretapping and analyzing the DOCSIS 3.1 Protocol
- Understanding why Vodafone does not support IPv6-addresses while the router is in bridge mode (to be proven: IPv6 is used for VoIP-Telephony and is therefore terminated at the TG3442 running in bridged mode)
