Hello Experts,

Can someone let me know if its possible to configure interfaces on ASA with same named interface e.g.

interface Ethernet0/1
 description Connection to Inside A1 LAN
nameif inside
 security-level 100
 ip address 192.168.170.1 255.255.255.0

interface Ethernet0/2
 description Connection to Inside B2 LAN
nameif inside
 security-level 100
 ip address 10.25.0.1 255.255.255.0

Will the above work?

Regards

Is your end goal to permit traffic between the two interfaces with the same security level? Please read http://3cvguy.com/cisco-asa/

If it's just for aesthetics, I don't think you can name 2 interfaces the same name.

Hi netcmh

Thanks for responding

I followed the instructions in the link but it didn't work, see below;

tina-asa(config)# same-security-traffic permit inter-interface
tina-asa(config)# int eth 0/2
tina-asa(config-if)# nameif inside
ERROR: Name "inside" has been assigned to interface Ethernet0/1

You cannot name both the interfaces the same name. What is your requirement for doing this?

Netcmh,

OK, I'm getting confused here:

ASA-CLI (config) # static (server,storage) 192.168.0.0 255.255.255.0 192.168.0.0 255.255.255.0

ASA-CLI (config) # static (storage,server) 192.168.2.0 255.255.255.0 192.168.2.0 255.255.255.0

Is (server,storage) the nameif for server and storage?

I have changed it on the second interface to 'newlan'

But I can't get the static to work, see above

If both interfaces have the same security level (but different names) and you have "same-security-traffic permit inter-interface" enabled then you should be able to move traffic between those interfaces.

Is that not working?

Hi Don,

Apparently, I need the following configuration to make it work:

static (inside,newlan) 192.168.170.0 255.255.255.0 192.168.170.0 255.255.255.0

But it still doesn't work

You will also need:

static (newlan, static) 192.168.170.0 255.255.255.0 192.168.170.0 255.255.255.0

Sorry, I was away on a meeting. Were you able to get the traffic flowing?
