Can I set the same security level on two interfaces in PIX, ASA and FWSM?

If two DMZs had same security level, what default rule should be? allow or deny any any in two directions ?

Thanks very much!

Low to high is allowed by default, and high to low is disallowed by default.
Same to same is also disallowed by default, unless you have issued:

same-security-traffice permit inter-interface

This is from the ASA docs, I don't know about the older PIX, but Cisco docs do recommend not relying on this and using explicit ACLs. Hope that helps.

Sorry, I reversed the correct logic in the first sentence.

Correction: High to low is allowed by default, and low to high is disallowed by default.
