Outbound NAT to child VLAN

  • Hello,
    I need help with issue with Outbound NAT.

    My pfSense has two fysical interfaces:
    WAN: em0
    LAN: em1

    Here is outbound nat to the Internet OK. But !

    LAN (em1) has many children – VLANs . If I use simple routing + rights rule on firewall, everything is ok. Communication between VLANs is established.
    But now i need communication from LAN (em1) to the VLAN (em1.8) via Outbound NAT, result is still only routing, not NAT.

    Please, say me, where is the fail ?
