Forwarding VLAN on WAN

Wed Jun 11, 2025 12:19 am

Dear everyone!

I am now familiar with Mikrotiks for a few years, yet VLANs are still messing with my brains. Recently I did find out VLANs, that one of our ISPs are using, so that I am able to get rid of their Modem+Router and bring the internet directly to Mikrotik device. The situation is as:

On WAN port I put on VLAN for Internet
And the same VLAN for IPTV

I have both correct info, and I know it works, because I tried it to bridge with other ETH interfaces, and everything works fine.

Now the real question for me is: when I bring in the internet via NET vlan, I call out with PPPoe, and I get nice Route automatically. BUT! IPTV VLAN is not requested to dial anything I just put it on
WAN interface and there it is. My question here is, how can I forward those VLAN via hardware filtering to other devices? How can I do that? What do I put in the bridge?

Let say I want to use another ROS switch, where I use 4 ports for TV, situation.

Thank you!

Here is my answer in another thread that can also be applied to your setup viewtopic.php?t=217211#p1146420

Of course, you can have more ports in your VLAN aware bridge, not just ether1 and ether2 like that thread. You can distribute that "VLAN2000" to other ports as you wish, tagged or untagged, same with the IPTV VLAN. And your equivalence to "VLAN1000" is probably tagged on the WAN port instead of untagged.

But the general, the idea is still the same: make your WAN port menber of the same VLAN-enabled bridge as your LAN ports. The VLAN that you use to dial PPPoE only has the WAN port and the bridge port as member, so on Layer 2 it's properly isolated from the rest your LAN. The IPTV VLAN is bridged and can take advantage of hardware offload if your device supports that.
