UPnP & NAT-PMP not working



  • I have a Virtual Pfsense firewall running on vmware esxi 6.5, the Pfsense version 2.3.4. I need to allow port 1500 on additional network (vLAN), I configured UPnP & NAT-PMP but unable telnet port 1500, also do not see any session in status "UPnP & NAT-PMP"

    Following are the interfaces configured on the firewall

    1. Wan
    2. Lan
    3. Lan1 - /24 network I need to open port 1500

    UPnP & NAT-PMP configuration :

    Enable UPnP & NAT-PMP = enable
    Allow UPnP Port Mapping= enable
    External Interface = Wan
    Interfaces = LAN1 (Selected)
    Default Deny = Deny access to UPnP & NAT-PMP by default. Checked
    ACL Entries = allow 1024-65535 10.40.40.0/24 1024-65535, even tried 1500 10.40.40.0/24 1500 still no luck.

    Any help or suggestion please
