Problem with MAC address and Cable modem

Post by siosios » June 17th, 2019, 1:22 am

I have the cable modem in bridged mode since it comes with a built in firewall (which is off), so my question is how to get the actual MAC addresses from the connections?

Im not sure which MAC Address you need. Some cable providers works only with the first card after booting the modem and some has hardcoded the address of the supplied router.

The cable network itself has no mac addresses, they are Ethernet only.

sorry arne,

i dont think i put out there exactly what i was thinking. the mac address of my cable modem is the only thing shown in the firewall log instead of the mac address of the clients that are connecting to the firewall or am i totally wrong in my thinking on this.

The mac addresss is only valid for the local ethernet segment. If there is any router between your system and the client you not see the mac address of the client.
