IP Address assignment on LAN Interface ASDM /CLI

[amh4y0001]

Hi,

Have Cisco Firepower 1200 /ASDM and inside Ethernet 2 (inside) has 192.168.1.x IP address by default for the management purposes.
Question:
a) Is this port (Ethernet 2) and remaining other ports (Ethernet 3 - Ethernet belongs to same vLAN?
b) Can I leave Ethernet 2 (inside) as it is with it's default IP addressing scheme, or there is some other best practices?Firepower, Cisco Adaptive Security Appliance (ASA), Other Network Security Topics
c) How I can use Ethernet ports (3 - as LAN ports, same vLAN (but different from what Ethernet 2 belongs to) and IP address assignment etc.?

Thanks!

@amh4y0001 no need, there is very little configuration on your ASA.

The DNS configuration on your ASA is for if the ASA resolve DNS names, just ensure your clients all have a DNS server configured.

@Rob Ingram Thanks.
And if I want to have two ports to belong to the same networks if it's really possible?
