21.7 Legacy Series / Bridge of VLANs, no internet
« on: August 08, 2021, 03:01:16 pm »
Hello
I opnsense installed on a box with an intel 4 NIC. I have multiple access points connected directly to ports of this NIC. I want to create VLANs which are available to all access points connected to these 4 NICs ports. I do this so I can create WiFi networks for guests and for IoT, available on every access point.
So far i have created 4 VLAN interfaces each with their own assignment and then bridged them together (I had to do this in order to make DHCP work, i first tried making a vlan directly on the LAN bridge (which bridges the NICs 4 ports), but DHCP didn't work that way). On my access points (OpenWRT), I configured the right WiFi networks. My devices can connect and get an IP in the right DHCP range, so this is working. However, none of these devices can connect to the internet (or ping the router). My bridged VLAN has a pass all rule in the firewall, so I don't know why it's not working.
I found this post of someone having the exact same issue, but no solution is provided: https://forum.opnsense.org/index.php?topic=7359.0
What am I doing wrong? I also don't understand why I don't find more information about this as this seems like something a lot of people would do.
