Following is my config on 5525-X firewall,
interface GigabitEthernet0/1
no nameif
no security-level
no ip address
!
interface GigabitEthernet0/1.100
vlan 100
nameif vlan100
security-level 100
ip address 10.10.10.1 255.255.255.0
!
interface GigabitEthernet0/1.200
vlan 200
nameif vlan200
security-level 100
ip address 10.10.20.1 255.255.255.0
----------------------------------------------
PC with IP address 10.10.10.12 tries to ping 10.10.20.1, I am getting the following error
%ASA-6-110002: Failed to locate egress interface for ICMP from vlan100:10.10.10.12/1 to 10.10.20.1/0
From the ASA itself I can ping both interfaces. But extended ping from vlan 100 to vlan 200 fails with the above error as well.
