Captive portal to LAN routing

  • Hi,

    I'm trying to solve this for some time now but i can't achieve it. So I ask here (I hope I'm in the right place)

    I have the following setup:

    LAN (on vlan0)
    WAN (on physical interface)
    WLAN (on vlan1)

    I'm running a "Captive portal" on WLAN to provide Internet access to our visitors. Without any access to LAN.
    But now I need to provide a printer to our visitor. The printer is in LAN network but visitors in WLAN.
    I tried a 1:1 NAT but it does not work.

    Is there any way to achieve this ?

    Thanks a lot for your help !
