Is it possible to configure the HWIC ports as LAN ports? For example, i have the 1921 behind a consumer router so i know its a double NAT situation, its for a LAB, i want to be able to connect client devices on the 4 ports of the HWIC segregated from home network.
Is that possible? Do they need to be assigned IP addresses like a layer 3 port or can they be DHCP?
Thank you in advance

Have you configured L3 switches? If so, it's pretty much like that.
I believe (?) the router's SVI will support DHCP and NAT. However, you may find the SVIs don't offer all the features the built-in router ports do.

Unless you HWIC is L3 Ethernet, you'll need to use SVI(s), and VLAN(s).

Ok thanks
I have very little experience with L3 switches.
Appreciate your time

Ok, in Packet Tracer, I selected a 1941 (as it doesn't offer the 1921, and the 1941 is just the more "powerful" model.
I then installed a HWIC-4ESW in the first

Would you like to enter the initial configuration dialog? [yes/no]:

model slot, and booted the router.
During boot up, we "see" the 4 module ports:
To use much like a router port, you assign a VLAN to one of those ports and then assign a SVI:

Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
