Hello Community!

I have a problem with a 450G (4.11) with a Bridged VLAN Config.

Interfaces:
ether1 (MTU 1500)
ether1.mgnt (VLAN Interface ID 11) (MTU 1500)
ether2 (MTU 1500)
ether2.mgnt (VLAN Interface ID 11) (MTU 1500)

Bridges:
bridge_mgnt (MTU 1500) -> Ports ether1.mgnt, ether2.mgnt
bridge_untrust (MTU 1500) -> Ports ether1, ether2

IP-Adresses:
10.30.1.12/24 on interface bridge_mgnt
91.135.180.12/27 interface ether1

when bridge_untrust ist deactivated
I can ping from my firewall, which is connected to ether1, from the VLAN11 to 10.30.1.12
I can also ping to 91.135.180.12 via ether1 (without vlan)

when I activate bridge_untrust
I can ping to 91.135.180.12
But I can't ping 10.30.1.12 any more. The Packet-Sniffer shows that even no ARP Request is answered, when I ping from the Router to the gateway 10.30.1.254

Do I have problems with the MTU when I bridge Untagged and Tagged Interfaces on the same ethernet ports?

Thank for your help.

It is not possible to bridge vlan interface and physical interface on which vlan is created at the same time.
Currently there is no solution for such setups, except to use managed switch.

try to create one VLAN interface on the bridge, not on ethernets =)

Hello Chupaka!

After hours of thinking, I tried this and it worked.

So i bridged the physical interfaces, and then created the vlans on it.

Thanks for your help!
