Here is the setup that is currently working but not what I need. I have a DHCP server upstream outside of my control giving public ip addresses. On the core mikrotik router, I have a port that I bridged with a vlan. Downstream on this vlan another router gets a public ip address. This works fine but I need to have this connection going through the radius server on the core mikrotik router to obtain the amount of data transferred through the link. The change I need to make is to have the downstream router use pppoe to connect to the core mikrotik router and still get the dhcp address being handed out by the upstream DHCP server. I tried various test configurations on the core mikrotik router but they just don’t work. MIkrotik v5.24 does not allow adding a pppoe interface directly to a bridged interface. Does the newer versions of routeros allow pppoe to be added directly to a bridged port? I need some help or a direction to refocus my researching and testing.
This works but does not use radius so no accounting can be done hence not what I need.
Internet(DHCP server) ------- Core Mikrotik Router ( bridge1 (eth3 and vlan1) ) ------- (no authentication) downstream router.
This is what I am trying to achieve/need.
Internet(DHCP Server) ------ Core Mikrotik router ( bridge1 (eth3 and pppoe server) ) ----- (authentication) downstream router.
