Captive Portal for IPSec-connected guest network

[setchi]

Hi,

We are running a wifi guest network with a voucher-enabled captive portal at our main site for several months without any problems:

Internet –- pfSense(Voucher-CaPo) --- Guest-WiFi-MainSite

Now we got a request from one of our remote sites to establish a voucher-based guest wifi at that location also.
We now tried to connect the remote guest-networks with a IPSec-Tunnel, but the clients at the remote guest-network will never redirect to the portal's login page - they have immediate access to the internet instead:

Internet --- pfSense(Voucher-CaPo) =====IPSec-Tunnel===== RemoteFirewall(nonPfSense) --- Guest-WiFi-RemoteSite

Is there any possibility to force the incoming IPSec-traffic to terminate on the captive portal?
Did anyone try to do this?

BTW: I don't like to get any "Install a additional pfSense Box at the remote site"-advices :)

Thank you
