I believe I have found the problem:

It seems that when a Bridge is created, the Internet Port of the main Deco is added automatically to the bridge. In my case, because I was also connecting the second port of the main deco to the same HUB where the Internet port is connected, it causes a broadcast storm (loop) and things don't work

Can someone please advise if this is the expected behaviour or is it a bug ? I don't really think this should be the correct behaviour. The correct behaviour should be that ONLY the ports added to the bridge should be part of it

@Support ? Anyone ? Please advise ?

Thanks

Thank you for your reply. 

My use case is #2

I have all my clients behind the Deco MESH and the main Deco has a cable connection to the Router (to the 192.168.10.0/24 network - as explained above)

What I want is for 2 remote clients to connect to 2 ports of the remote Decos and be Bridged to the Deco port that connects to the 192.168.10.0/24 network so that these 2 clients are in the 192.168.10.0/24 network instead of being in the Deco Routed network

As explained, I had this configured for sometime where I was adding the second port of the main deco to the bridge, together with 2 other remote ports on other decos. and then connect the second port of the deco to the switch (so that all these 3 bridged ports would be in the 192.168.10.0 network). This worked for sometime but a couple of days ago stopped working and I started getting broadcast storm

What I realized is that it appears that the remote bridged ports are ALSO bridged to the main deco port that connects to the router / switch and as such adding the second port to the same router/switch causes an issue

I just want to understand if this is the expected behaviour - It doesn't make sense to to have the main deco port ALWAYS part of the bridge - This is not documented anywhere and the behavior doesn't make sense (to be honest in my case it's ok and I can work with this but the majority I would expect that only the ports I make part of the bridge, by configuring them in that bridge, become part of the bridge and not automatically add other ports just like that)

Can you please advise ?
