I have a Mikrotik CRS109 which I plan to use when fibre is installed (they have marked my street for the drilling - yay)
Ive recently moved to this house, previously I had Vodashame Cable which the Mikrotik was great for. At the moment to get VDSL I acquired a Draytek Vigor 2750 and the poor Mikrotik has been acting as basically a switch. I Followed some instructions from snappernet to turn the Vigour into a bridge and have an alternative device into the PPPoE client, this didnt seem to work on my mikrotik, but plugging a Laptop in and setting up a PPPoE connection into the modem did work, so I can assume by that that the Draytek modem config was correct.
The Modem was setup to do this by putting the modem into bridge mode, disabling the PPPoE dialer and enabling multi-vlan bridging the WAN and Port 4 of the modem and tagging port 4 with VLAN ID 10. This worked for the Windows Laptop to PPPoE without havng to tag it with vlan ID 10.
On this principal I setup a PPPoE connection on the Mikrotik with my credentials and the interface ether1 (standalone port not connected to a bridge or switch port) which was linked into the same port on the Draytek. This just did not connect at all.
The PPPoE interface as set up with my given username, password, profile default and 'use peer dns' and 'add default route' checked with all authentication methods allowed and interface was ether1.
I realise when I go for UFB ill need to add a vlan with vlan ID 10, create a bridge, add ether1 to it, and attach the PPPoE profile to the vlan with ID 10.. but as the modem is doing all the tagging and untagging its not needed yet.
Has anyone successfully configured a mikrotik router to use Fibre and have the PPPoE dialer working on it? most of the stuff ive worked thru says t use l2mtu of 1522 but my rotuer seems to fix that on 1584 and it cannot be changed, not sure if this is the issue
