Re: Trunking to a PIX515 firewall

I have a question about extending trunks to a PIX515 firewall.

We have a scenario where we are needing to trunk to switches that are behind a PIX515 firewall. From my readings this does not seem to work. Any suggestions or work arounds.

Hi,

PIX 6.3 supports 802.1q tagged interfaces. I don't know exactly what you are getting at with respect to "needing to trunk to switches" but hopefully this helps. Good luck.

If you need to have a trunk between two switches with a PIX in the middle, that is not going to happen.

Trunks operate at layer 2, and the PIX is essentialy a layer 3+ device.

Is there any work around or possible solutions that will allows us to extend VLAN's behind the PIX or rather trunk to the switches behind.

Nope, this is not possible.

Why exactly do you need this?

I can not think of any case where you definately would need to extend vlan´s to switches behind a PIX. So I´m real curious why you need it. Can you tell more about the motivation for this?

Kind regards,

Leo
