Bridge interface is not working with vlan

Joy Joy1

Dear Team,

We have to add two interface as a bridge - like A1 and A2 with sub interfaces (Vlan interface).

Below are the configuration steps which I had created yesterday for bridge interfaces-

1. Created Zone (Common ZONE)

2. having created Zone, added vlan in ZONE

3. after that I added port A1,A2 in bridge interface with Common ZONE.

Communication was not happing.

As I think there will be no policy required for bridge interface.

Even though I had gone through below documents but couldn't understand properly. Is there anyone who share any article or scenario with an example.

Thank you.

    This is a great diagram and helps to understand your setup.

    But I really meant your configuratioin conecerning those two interfaces and the vlan details on your Sophos firewall. You could post screenshots of the edit view here.

    In a bridge you will need firewall rules to allow traffic to travel from one port to the other (and back). So make sure to allow traffic using a firewall rule something like:

    source: common zone
    destination: common zone
    service: any (or be more restrictive if necessary)
    Allow
