i'm not sure if I understand exactly what the problem is that you are seeking help with, but by design a transparent bridge will broadcast to all connected ports any frames that it does not recognize an internal address associated with it. &nbsp;Therefore, the ip table will not cause the bridge to block any traffic, rather quite the opposite. &nbsp;Not sure if this is any help...

I already solve the problem.<br />
<br />
Both bridge interfaces does not have an IP address and the iptables is not capable to &quot;see&quot; this traffic.<br />
<br />
I installed ebtables (ebtables.sourceforge.net)<wbr /> and the probles was solved.<br />

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection.  Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.
