Multiple VLAN Connectivity - ASA 5516

‎05-04-2016 09:15 AM - edited ‎03-12-2019 12:42 AM

I have an ASA 5516 and a Catalyst 2960 X. I have created 2 sub interfaces

192.168.11.0/24 and 192.168.12.0/24 on interfaces gi 1/1.11 and gi 1/1.12.

I have a cisco 2960 x switch connected to gi 1/1 interface of the firewall. I connected one laptop in VLAN 11 and able to ping 192.168.11.1 but not 192.168.12.1. Can you tell me what is wrong in the config?

Hello; 

Nothing, you did nothing wrong. You cannot do that on an ASA firewall. You cannot ping any far-end interface of the firewall, just the IP on the interface that you are, well facing... lol. 

Plug a host there and try to ping it... it will work, I guarantee it... 

Mike.

Hi,

As per the network requirement description and configuration above, I understand that you have a laptop in connected to vlan11 (ASA ip: 192.168.11.1 255.255.255.0; name:inside)  and you are trying to ping other interface which is in vlan12 (ASA ip:192.168.12.1 255.255.255.0 ; name: inside2)

As per ASA design, one cannot ping the far side interface. So you can ping inside interface from a machine in vlan11 and can ping interface vlan12 from a machine behind inside2 interface, but user in vlan11 will not be able to ping vlan12 interface of ASA(inside2 interface) and vice versa.

Hope it answers your query and feel free to correct my understanding of the issue.

Thanks,

RS
