V18 Adding VLANs to Bridge Pair

Hi,

I setup this test environment

On XG port 3 and 4 are bridged and add VLAN 301-304

I have firewall rules to allow access between VLANs. 

I have 2 x Layer-2 switches (no stacking), each has VLANs 301, 302, 303, 304 on uplink trunk port connect to the bridge interfaces

I turned off all security features like IPS, content filtering and malware scan when conduct these tests.

I experiencing the following result does anyone can tell what's wrong with this setup?

Thanks
