VLAN Setup Question

[mintchipmadness]

Hello All,
I am new to networking and I have a question regarding setting up vlans. I currently have a trunk port from my opnsense box to my switch (Brocade ICX7250) with 3 separate networks. The networks are vlan 5, 10, and 15. vlan 5 is setup as the lan with the other two as separate networks. I originally setup the lan as untagged and the other two networks as tagged vlans but I was hesitant to go that route since I heard that dual mode traffic is not optimal. Should I leave my setup as tagged traffic only or would it be best to have my lan network untagged with the other networks tagged. The major question is why is one better than the other? A quick visual of my current setup between the switch and router is below. Thank you for your help.

Switch port 1/2/1 ----------> opnsense lan interface
vlan 1   Untagged                         vlan 5 (LAN)
vlan 5   Tagged                             vlan 10 (Network 2)
vlan 10 Tagged                             vlan 15 (Network 3)
vlan 15 Tagged

duel traffic does not mess me up at all but its a homenetwork  not the huge times

you will need 1 trunk port  and that should be good if some of the vlans are upstream if not just dchp each of them (if thats what you are looking to do)

i have 11 vlan myself using 4 currently plan to expand to 6 soon but i have the work out for the 11 now
as long as your OUT port is trunked/tagged you should be ok
every other port can just be assigned to vlan (x)    your issue will be with the firewall rules a issue im trying to solve myself right now.

in order to block them off you ether have to say block all local or set up each rule im not sure tho working that part out.
