I upgraded a test PIX 520 from V6.1(3) to V6.2(1) and from pdm V1.1(1) to V2.0(2).
Only the inside interface is enabled on this test PIX FW.
My question is: Why in PDM V2.0(2) nothing is shown under system properties - category interfaces ?
All the rest looks fine. Also in the config (f.e. show conf) the interfaces are there. Is this a bug? Any similar findings in your environments?
