FWSM Configuration with Virtual Firewalls

Unanswered Question
May 14th, 2008

Hi,

I want to implement two layers of firewalls, using two FWSM contexts. I know that two virtual firewalls cannot be cascaded (usupported design), but in my case, both contexts do not share any vlan, so it is not pure cascading. Here is what I would like to install :

VLAN100--FW1--VLAN200--MSFC--VLAN300--FW2--VLAN400

The inside interface of FW1 is VLAN200 and the inside interface of FW2 is VLAN400.

Is this configuration suported ?

Thank you

I have this problem too.

I think its possible without any issues. At hte same time you can now configure a single FWSM to behave as multiple virtual firewalls.
