@raboud
do you think this is enough for your part ?!
begin to describe your problem accurately, etiquette is very important
just so you write in a nearly 1 year old thread.....
-What would you like to know?
-since there have been a lot of updates in 1 year, it may no longer be up to date what you would like to know

Just forget about OPT1 being a member of the switch VLAN.
That XG-7100 unit has a built-in switch. Bridging that with OPT1 will only slow things down as you will no longer be using switch hardware but will be using a software/CPU bridge.
If you need OPT1 connected to a switch, connect it to a switch.
If you absolutely need those XG-7100 ports to be on the same broadcast domain as OPT1, I would disable the trunk links back to pfSense (no 9t,10t tagged ports on the built-in switch on that VLAN) and patch it to your external switch.
