Mac address problem with DHCPv6 on Dual Stack

RouterOS General
1

Hi,

My MK RB2100 has version 6.4. I have a dual-stack (ipv6 over pppoe) scenario
and i have a problem with the dhcpv6 request on the MK.
The pppoe session is established and use mac-adress d4:ca:6d:40:28:08 (mac from ether1-wan) for pppoe.
Now the dhcpv6-client sends out a request over the pppoe-session but uses a different mac adress 00:0c:42:ae:62:ff
as source. My ISP want that the pppoe-mac-address and the ipv6-mac-address must be the same.
How can i change the ipv6 (dhcpv6-client) mac address 00:0c:42:ae:62:ff ? I didn’t find it in the config.

Thanks,

Bob

So my last solution was to change the mac-address from ether1-wan to be the same as the dhcpv6-client.
It’s not easy to find directly the dhcpv6-client mac address, it’s a dirty trick but it works. :slight_smile:

Thanks,
