Hello!
My first post in forum. I have one question. Im using RouterOS v6.43.12. I want to send out (egress) both untaged and taged traffic to the same interface (in bridge vlans section). So, I can then in other physical switch join this traffic to 2 different vlan groups. Can I do this? For ingress I anyway can use unlimited vlan (to send them all forward to destination untaged).
Why do you use the most inappropriate forum for this question?
There is a General and Beginner Basics forum, both would have been reasonable choices.
One also expects some level of effort to understand the topic prior to asking questions so recommended reading includes:
https://wiki.mikrotik.com/wiki/Manual:Interface/VLAN
http://forum.mikrotik.com/t/using-routeros-to-vlan-your-network/126489/1
There is not written can I send taged and untaged traffic to the same interface.
Then read more slowly and pay close attention to the examples in the second link.
