I run my computer in a Live Linux CD/USB environment, and occasionally when using Tor modify (spoof) my computer's NIC Mac address - not my hardware router's Mac address. Upon login to the administrator account to my router, I notice that quite a number of network records of my previously changed Mac addresses (for my computer) remain as a side effect and are not expunged after the session where both my hardware router and computer are powered off. The router login is to a GUI interface, and there does not appear any way to expunge these records. Perhaps one way would be to reset the hardware router to its factory defaults after saving the configuration modifications I made to improve its security and close the ISP's backdoor port. Presumably, the router's configuration could be restored (from the computer) since when the configuration is saved it is saved on the computer. Has anyone noticed this example of spoofed Mac address router records (for the computer's NIC) on the router, and how would I go about removing these previous (spoofed) Mac address records from my hardware router in order to remove any association with them wrt any discovery process for associations with them that presumably would break plausible deniability.
