Good day,
It has been 2 days of me trying to get things working on my network setup and I think I am hitting a mental block trying to understand why Ether 9 doesn't work like the other untagged ports.
Topology.
Pfsense as firewall, untagged is main lan and then created vlan id 666 that will be trunked to a CRS326 running RouterOS, which in turn Trunks that to an RB4011 in a different room.
I finally get everything working using this way.
on CRS326 I added VLAN interfaces on eth1 (from pfsense) and on eth2 (going to RB4011) I did not add them under bridge like some suggest that didn't work when I tried or I might have missed something, I tagged eth1 and eth2 with vlan 666 on VLAN (Bridge window) and dynamically got an entry of untagged ports for vlan id 1.
on the RB4011 I added VLAN interface on eth1 (from CRS326) and then tagged eth1 for vlan 666 and then for access ports eth2. eth3 and eth9 I changed pvid to 666
I hope I am not missing any extra info that would be helpful but my issue is, when I plug a device say a laptop to eth2 or eth3 it gets an ip from pfsense from the vlan interface / dhcp that I set, but that doesn't happen on eth9.
I am still new to networking, and literally 2 days new in VLANs at least first time trying it, I know the concepts.
I tried changing the cable and it wasn't the case, the port works normally if I remove the vlan 666 and it will get regular ip from dhcp but when I make it exactly like eth2 and eth3 settings it just doesn't work.
I can use it as is, but I want to know why, is it my mistake, something I missed or is it with the router it self.
best regards,
