Two inside interfaces on the firewall sharing the same outgoing interface

conceptzone — Mon, 11 Mar 2019 20:37:33 GMT

Dear All,

Currently, I have one inside interface and one outside interface configured on my ASA. the requirement is to configure a second inside interface with different subnet and it should share the same outside interface (PAT) going to the internet.

The current related configuration

interface Ethernet0/0
nameif outside
security-level 0
ip address A

!
interface Ethernet0/1
nameif inside1
security-level 100
ip address B

!
nat (inside1) 1 0.0.0.0 0.0.0.0
global (outside) 1 interface

The future expected configuration (Please correct me if I am wrong and let me know if the following nat command would affect the first one)

interface Ethernet0/2
nameif inside2

security-level 100
ip address C

nat (inside2) 1 0.0.0.0 0.0.0.0

Thanks indeed

Ismail
