Is it possible to force authentication for lan to lan traffic

[genfoch01]

I have two lans ( lan and lansec  as an example )
to isolate lansec fw rules to block access to LAN and also block access to the fw itself but does allow internet (WAN ) access.

I would like to set up something like captive portal  but have it authenticate traffic that goes from LAN to LANSEC. I don't want anything on lansec forced to authenticate to get onto the network. so this is clearly not the typical use for captive portal.

I unsuccessfully tried using captive portal but am not sure if this is the appropriate tool. Is there a way to do this?

as an example   if my desktop is on the LAN ( it did not need to authenticate to get onto the LAN) and I open a browser and point it to a server on the lansec network I'd like opnsense to authenticate me before allowing that connection.   

let me know if more detail is needed and thanks for your time.

Unlikely.
How about a LAN3 with captive portal that's the only network that can access LANSEC?

Thanks for the response. I really need to find a way to allow lan access the lansec I was hoping I could do this through opnsense. I think i'll try this with nginx proxy manager though I don't trust it (security wise ) as much as opnsense.
