Hi Bill,

Yes the mac is different:
Sep  4 10:29:52 anlpn35 dhcpd: DHCPREQUEST for 172.20.17.22 from
f8:0b:cb:4f:db:dc (PC7345) via 212.39.196.110
Sep  4 10:29:52 anlpn35 dhcpd: DHCPACK on 172.20.17.22 to f8:0b:cb:4f:db:dc
(PC7345) via 212.39.196.110
Sep  4 10:50:41 anlpn35 dhcpd: DHCPREQUEST for 10.101.90.45 from
d4:81:d7:77:15:16 via enp6s0
Sep  4 10:50:41 anlpn35 dhcpd: DHCPACK on 10.101.90.45 to d4:81:d7:77:15:16
via enp6s0

The difference is, the 172.20 Address is for a Cisco AnyConnect Client.
Actually Requested by the Firewall with a different UID for each Session.
MAC for all sessions is the same.
Nevertheless anlpn35 added the A Record for 172.20.17.22 why does it say
DHCID not mine??

Tom
