Hi there,


Vodafone have 'upgraded' my internet to FibreX 200/20 and with it replaced the various pieces of equipment I had with a technicolor cable modem and seperate router. I have a Mikrotik router configured and managing all my home devices well and do not want to transfer them all to the new router (which does not seem to like the number I devices I tried to connect).


I have been trying to set up the Mikrotik to directly connect to the technicolor cable modem (following this guide -, but also setting up dhcp client for IPv6) but cannot get a working connection.


I have:


1) connected the Mikrotik directly to the technicolor cable modem


2) run through the guide above to enable vlan tagging / dhcp / changed firewall rules etc (and enabled ipv6 too)


3) confirmed I am receiving an IPv4 and IPv6 address in the dhcp-client section of the mikrotik


4) restarted everything just in case


5) failed to get a connection to the internet


6) tried factory resetting the mikrotik incase any old rules were breaking something


7) still failed to get a connection to the internet


This has all got a bit beyond me - I have enough knowledge to follow various guides, but not enough to troubleshoot / diagnose what is actually happening here (i.e. enough knowledge to break something... but not fix it). From the guides I have read, once I have confirmed I am getting dhcp to provide IP address from the technicolor / vodafone, and provided I have the firewall configured correctly, I should be getting internet, but I am not.


Any help would be appreciated.

Did you read through the IPoE instructions here? 



Thanks michaelmurfy


I did - and followed through exactly first time - second / third time (after reset mikrotik), the first highlighted rule (Drop all from WAN) was no longer there. I had the following (and have tried the drop invalid both with the Vlan interface as in interface and with nothing):

I do note I have not changed any of the IPv6 Firewall rules, which look like this:

I did update the NAT masquarade rule (as follows):


Click to see full size


I still do not have internet (but still showing has received IP address in DHCP Client for both IPv4 and IPv6).


Thanks very much for the assistance - happy to provide more screenshots / try out ideas.

Figured out what was going wrong - 2 of the default rules once resetted the Mikrotik were different from what needed to be. What I did to fix was:


1) Create a new firewall rule with: Chain=input, In.Interface=VLAN (my default firewall rules did not have this rule and I was editing another rule I should not have); and


2) change my Masquerade rule, which was pre configured with an out.interface.list - once removed the out.interface.list, internet came back up.


Hope helps someone else - the original Mikrotik guide here ( worked a treat, my default config was just starting from a different point.


Glad I have my lovely stable and secure router back!
