'Assigned IP Address' of '0.0.0.0'?

[bswitzer]

I have something like 60 PIX 501's coming into a 3.6.1 vpn 3030 concentrator. The session list mostly shows the inside network address of the PIX, but some only show '0.0.0.0'. There is a public address, and bytes are being transmitted and received. The connection works.

Why is '0.0.0.0' not being updated and where can I look for further information?

There's been various bugs on this in various versions of code. Some include:

CSCdv36065, CSCdz04218, CSCdy27564, CSCdw13856

They are all cosmetic, so nothing to worry about. They're all fixed in 4.0 code so upgrading to 4.0(3) should resolve the issues you're seeing. As I said though, they're purely cosmetic, so unless they're really annoying you then you can leave things as is.
