Communication between two tagged interface

[freetomfr]

Hi everyone,

I have a problem with only two tagged interface. The problem seems to be very simple but after a lot of search I can't find a solution.

I have 2 interfaces :

• WAN : UNTAGGED on default VLAN (physical interface 1)
• OPT1 : UNTAGGED on default VLAN (physical interface 2)
• TG1 : TAGGED on VLAN 100 (physical interface 1)
• TG2 : TAGGED on VLAN 100 (physical interface 2)

I bridge WAN AND OPT1 to allow communication and DHCP and that's work great.

I tried to bridge TG1 and TG2 too to obtain the same result but nothing work.

Do you have a solution to this very simple problem?

Thanks

Nobody has an idea to do this?
