Multiple DHCP Discover/Requests within same second, Delayed ACK's
We are using kea version 1.5 and planning to upgrade to Kea 1.8.2 version. Though we have certain findings and would like to discuss and understand in detail the working of Kea as we recently faced an issue where clients were not getting IP address. when we digged more it was found out that palo alto firewall was discarding the ACK packets as it was seeing it was a server generated traffic. When we captured packet on DHCP server we could see and observe multiple below things. please help us to understand the behavior.
- Multiple DHCP Discover/Requests within the same second
- Delayed Acks from DHCP server but no delayed Offers
- Multiple Requests after successful DORAs (be:fd:97:a5:3c:00)
- Candidate who sends huge request to server : 10.26.164.81 (002315ca991c)
Kea Version- 1.5.0P1capture117-2.pcap
