Deco M9 Plus MAC adress for public IP
Hello. I have now my 3 pieces of the Deco M9 Plus set up at home. My primary Deco, as router, is directly connected to my ISP outlet with ethernet cable. The other two Deco M9 Plus are connected in star formation. I have disabled IPv6.
Now, my ISP offers me two public IP adresses and for that they need the MAC adress of one of my computers and the other MAC adress id the one of my M9 Plus router.
With the MAC adress of my computer I can connect my computer directly to my ISP outlet just in case my router would break down.
With the ethernet MAC adress of my Deco M9 Plus router I now want my Deco M9 Plus directly connected to ISP outlet and have the second public IP-adress that my ISP offers to me dedicated to my M9 Plus router.
Now I have the following problem: my ISP does not recognise the MAC-adress labled on the bottom of my M9 Plus but instead a second MAC-adress that only differs on the last position of the stated MAC-adress.
Let's say the given MAC-adress is aa-bb-cc-dd-ee-1C then my ISP recognises aa-bb-cc-dd-ee-2C instead. Only the very last part of the MAC adress is different.
My question now is: does the M9 Plus have two physical eternet MAC-adresses? What MAC-adress should I tell my ISP to dedicate to my offered public IP-adress? Please advise me with som help on this!
Thanks in sdvance for your help.
