Cisco ASA Erase Configuration

Hi Rene

I have this Cisco ASAv version 9.5.1

I am trying to set the management interface with ip address 10.8.32.199 and gateway 10.8.32.1 with mask 255.255.240.0

show running-config interface gigabitEthernet 0/0
!
Interface GigabitEthernet0/0
 dewscription LAN Interface
 nameIf Inside
 security-level 100
 ip address 10.8.32.199 255.255.240.0

show running-config interface gigabitEthernet 0/1
!
Interface GigabitEthernet0/1
 dewscription WAN_Ingress Interface
 nameIf Outside
 security-level 0
 ip address 10.8.80.66 255.255.240.0


show running-config route
route Outside 0.0.0.0 0.0.0.0 10.8.32.1 1

But this is not pinging 8.8.8.8

I have another ASA but that works .

How do i set the default gateway 10.8.32.1 on the ASAv ?

Thanks
