Can Blue Network be used like another network?

I am new to ipfire and was wondering if the Blue network can be used like a
second Lan network if I install a normal network card (non wireless) or does
it have to be a wireless card?

I would like to use ipfire but do not want to use
wireless cards. I assume I can connect any network card to a wireless
access point if I needed wireless.

I am coming from pfSense and trying to see if ipfire will work like
pfSense does?

Thanks,
James

Yes . Alot of us use a second nic as a blue zone.
With or with out a AP.
I prefer it let the AP handle wifi password .
Not sure of linux support of wifi cards. You can get an AP with WPA 3.

Yes it is possible.
You can look that up in de documentation.
