PA-500, PANOS 4.0.5, DHCP set to "auto", lease time all zeros, one IP pool (192.168.2.2-192.168.2.126) .
Recently I noticed that I was getting duplicate IP messages from Windows computers on my network. I found that certain devices were geting the same IP. I found that when plugging in two devices both got the same IP address.
Has anyone else seen this? It appears that a lease time of zero started behaving like a lease time of zero instead of unlimited. I have another PA-500 configured the same way with no problems.
Setting a lease time fixed my problem, but I'm curious why after more than a year of use the behavior would change, and why my other PA-500 behaves differently.
