Good Day All,
I have a simple topology with a Firepower 1010 locally managed. Here what the topo looks like.
I have port 1/1 configured as am access port on a vlan 2 ( outside - internet vlan )
I have port 1/2 as an access port on vlan 1 ( inside )
My DHCP have just a simple pool and configured on the inside interface ( 1/2 )
The inside is connected on a switch on vlan 1 as well .
Users when they try to get IP from the DHCP server on the Firepower are not able to and on top of that the inside interface mac address on a scanner we have internally was showed that all the IP on the pool were assigned to it. ( see the picture bellow ).
All the IP got the same mac which is the inside interface of the firepower.
Any help is appreciated .
Thank you in advance.
Solved! Go to Solution.
