I just find it bizarre that one machine works and one doesn't. I should add that I have also tried disabling UPNP and doing manual port forwards following the Netgate guide but it produced the same situation. Testing from CanYouSeeMe to my public IP address confirms this: Macbook Transmission shows Port Open but Mac Mini Transmission shows port closed: Test Port for both machines from pFsense is successful: UPNP status shows the two mappings operational:įirewall logging shows the packets to both machines being passed: On pfSense I have disabled both PFBlocker and Suricata. For troubleshooting I have disabled the Mac firewalls completely and disabled Little Snitch. For convenient remembering I have set the ports to 1004. I am testing Transmission bittorrent client on both, and only the Macbook works. To refresh the information in the UPnP Portmap table, click the Refresh button.I have a Port-Forwarding issue I just can't seem to resolve, whereby port-forwards (both manual and UPNP/NAT-PMP) work fine to one LAN machine but not another, and I can't for the life of me work out why.īackground: Home network 192.168.0.x all flat, no VLANs.īridged modem > pfsense router doing PPPoE for WAN > Netgear GS110TP switch > SFP > Netgear GS110TP switch > Ubiquiti access point and wired devices. The UPnP Portmap Table also displays what type of port is open and whether that port is still active for each IP address. The UPnP Portmap Table displays the IP address of each UPnP device that is accessing the router and which ports (internal and external) that device opened. If you notice that some devices are not being updated or reached correctly, it might be necessary to increase this value. The default value for the advertisement time to live is 4 hops, which should be fine for most home networks. The number of hops can range from 1 to 255. Hops are the steps a packet takes between routers. The time to live for the advertisement is measured in hops (steps) for each UPnP packet sent. Type the advertisement time to live in hops. Longer durations can compromise the freshness of the device status but can significantly reduce network traffic.ī. Shorter durations ensure that control points receive current device status at the expense of more network traffic. This value can range from 1 to 1440 minutes. The advertisement period specifies how often the router broadcasts its UPnP information. Type the advertisement period in minutes. If you selected the Turn UPnP On check box, the following steps apply to you:Ī. If the Turn UPnP On check box is cleared, the router does not allow any device to automatically control router resources, such as port forwarding. UPnP for automatic device configuration can be enabled or disabled. Select or clear the Turn UPnP On check box.īy default, this check box is selected.Select ADVANCED > Advanced Setup > UPnP.The user name and password are case-sensitive. Enter the router user name and password. Launch a web browser from a computer or mobile device that is connected to your router's network.To enable or disable Universal Plug and Play: However, in some cases, dynamic port forwarding is required. We recommend that you manually set up port forwarding instead of enabling UPnP. If you use applications such as multiplayer gaming, peer-to-peer connections, or real-time communications such as instant messaging or remote assistance (a feature in Windows XP), enable UPnP.Ī worm or malware program can use UPnP to compromise the security of your LAN. UPnP devices can automatically discover the services from other registered UPnP devices on the network. Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers access the network and connect to other devices as needed.
