I *can*, but then I'm back to where wifi can't talk to ethernet :\ The *only* way I can get things to work 'properly', is to disable STP on the main bridge which has all ethernet ports, and then create bridges for each vlan which needs to go to a wifi SSID ( and drop the vlan interface and the wifi into that bridge - aka the old way of doing it) - but then STP is disabled, which is horrible. (If STP is enabled on the main bridge, the network goes down as soon as I drop one of the vlans into one of the vlan-specific bridges..) This *shouldn't* be a complicated need - at it's simplest (i.e. the other two CRS109's in the house), it's to take three vlans in on a trunk (management, LAN and kidsLAN), put an IP on the management vlan, and bridge the LAN and kidsLAN vlans to two wifi interfaces. But I can't do that on a CRS109 anymore with hw-offload still enabled, and supporting STP. I MUST be missing *something*, surely? This seems like the target use case for the CRS109 - small office switch with wifi... just enough CPU to also support up to 50-100mbps of PPPOE.

I don't think you *have* to use this bridge VLAN filtering. Can't you just set up a common bridge with the eth's attached (to enable hardware switching) and then go into the switch menu and set up the VLANs the good ol' switch menu way?

Have been having MASSIVE performance issues all night tonight - as soon as say my macbook starts a time machine backup across the wifi, the whole network falls apart. Start to try to figure out what's going on, and realise hardware offload has somehow stopped working on the bridge ports since yesterday.
Discovering this wiki.microtik.com site that Mike wonderfully pointed me towards, I end up on
- and what do you know, enabling VLAN Filtering on CRS1xx/CRS2xx disables hw offload to the switch chip from the bridge.. What on EARTH were Mikrotik thinking implementing this hodge podge? Switch chip functionality worked PERFECTLY. Now we have this new bridge functionality that doesn't do half of what the switch chip functionality did, AND it doesn't support the existing hardware, so I can't get more than ~20mbps of *SWITCHING* out of my SWITCH. :(
I'm truly flabbergasted. I now have four CRS-109's which are basically glorified doorstops, as they certainly can't operate as switches if I want to keep them updated security-wise...?
Well, I've been awake for 36 hours. I'm going to bed. Will consider what to do with my home and DC networks going forward, tomorrow. :(

Hi Damien!
VLAN functionality supported by the bridge depends on the available switch chip, so it might be different for different routerboard models :-J Specifically, CRS1xx and CRS2xx are different than CRS3xx - other routerBoard models also depend on what chip is on board.
It's annoying, but I'm hopeful that they eventually implement some automation in bridge the same way they have done the port switching thing. Wiki.mikrotik.com has some half decent articles about this different methods for trunking especially.
I don't think you can do tag translation like you mention using bridge filter - for that job you'll need to go to switch menu and look under 'rule' tab.
Cheers!
Mike.

Ahhhhhh, right! I had assumed it was the same for the new bridges, as the filter unknown vlans setting on the switch chip config - if you enabled it, it would stop passing vlans you hadn't specifically defined. But yes, if it doesn't even turn on any of the bridge vlan functionality until that is ticked, that'd explain it!
So the last piece in the puzzle now... What function in this new bridge functionality allows vlan translation? i.e. say the port facing my provider has vlan 1275 on it, but I want to receive it into the bridge as vlan 35 (so that it's seen in RouterOS, and all other ports on the switch as vlan 35), how do I translate that in the bridge vlan config? With with the switch chip config, I'd simply have set ingress and egress translation rules for ingress 1275->35, and egress 35->1275 on ether1, and then dealt with it was vlan35 from
on. Is
there a setting in the bridge configuration for that? Or can I just keep using ingress/egress translations on the switch chip for that, alongside
configs?

Hi Damien,
What you describe seems 'expected' to me - 'vlan-filtering' is intended as a switch to enable/disable vlan awareness. Without it enabled, the bridge essentially doesn't care whether packets are tagged or not and forwards them like a normal bridge.
Unless I misunderstand your comment :-}
Cheers!

Just wanted to follow this up ;)
I've had niggling issues ever since with something of a split brain network - nothing on the wifi ON the main CRS109 has been able to talk to anything plugged into ethernet on the CRS109 (including devices on the wifi on the other CRS109's in the house). That's been a little annoying for
but we just switch to the time capsule's wireless and it works, so I've been lazy. Got home from work early tonight, and no-one was home for an hour, so
I'd fix it for good.
Pulled out all the existing switch chip VLAN configs (tagged VLANs, ingress/egress translations for untagged ports, etc), and replaced them with bridge port pvid and bridge vlan configs. Then spent an hour pulling my hair out with the entire network not working.
As it turns out, untagged ports will not always get their untagged ingress data re- mapped into the correct VLAN (it just completely gets dropped) unless you bite the bullet and set vlan-filtering=yes on the bridge. Then everything just starts working. Man that's a leap of faith though! I'm NOT looking forward to doing that on the CRS109 in the DC!
Just incase anyone comes up against it :D
