How to let one AP pass captive portal

[evewes]

Hello
I have several AP (Buffalo with DD-WRT). All AP have disabled DHCP and get IP from Pfsense.
I also have CP activated. All works very well for several years.

Now i have a need of one AP too always pass CP. I have tried to get clients to pass the CP but the only solution
i can find is too activate DHCP. That is a bad solution because i lose the possibility too handle clients in pfsense.

Is there any solution for this problem?

In the future when i switch router i will put in optional interface for wan and let the traffic pass without CP for
the AP.

I can't think of how you would accomplish this without either…

1.) turning on DHCP at the access point
2.) adding another interface to pfSense to connect the AP to
3.) adding a managed switch and creating a VLAN (not sure steps, but think you could do it.) attaching the AP to the appropriate port.
