Both UPnP & NAT should be turned on. What UPnP does is, it allows LW to communicate with the motorola device to request port(s) it needs to be opened whilst the program is running. NAT offers some protection against hackers. I am not sure about SPI or multicast.

Go to LW's menu bar, Tools>Options>Advanced>Firewalls & make sure UPnP is enabled. After any changes in the router, you'd need to save them. Some brands of router you actually need to reboot/restart them for changes to take effect. I am not sure about motorola, but worth a try.

I did some googling, & it seems (from my impression) multicast is not required & may result in degradation of performance. SPI can be disabled too. (Stateful Packet Inspection/Denial of Service firewall technology). SPI involves examining packets of data downloaded from the net via the router and denying suspicious packets, because the router knows what type of programs might be utilizing a particular protocol. Denial of Service attacks from hackers are but one type of attack the router helps to prevent via this technology. Turning the SPI firewall off in that router is not a significant difference in security. When you turn the SPI firewall on (Strict NAT), it starts inspecting the incoming packets and cross checks the source of the packet with the destination recorded in the NAT table. It will only allow packets through that came from the host that was the destination of the connection in the first place. (reference from discussion SBG900 drop-out/Reboot Problem - Cable - BigPond Different model Motorola, but similar slow problems whilst using p2p. Most of them port forwarded.)

Failing all of this, you may need to port forward.

Do you use wireless connection from the Motorola or via ethernet cable? The motorola 900 seems to struggle with p2p use when used in wireless mode. Same might be true of yours.



I found this on a particular site, not sure if it applies:

1. Select "Start" -> "Settings" -> ''Control Panel'' -> "Network and Dial-up Connections"
2. Right-click "Local Network Connections" and select "Properties"
3. Select "Advance" tab
4. Deselect the "Internet Connection Firewall" option
5. Click "OK" to confirm your changes and exit the panel


1. Launch the web browser from the computer that is connected to the Motorola SBG1000.
2. Type in the IP address <http://192.168.100.1> on the address bar of the web browser and press <Enter>
3. Login to the admin page of the Motorola SBG1000. The default User ID is <admin> and password is <motorola>
4. After you have logged in, click on the "Firewall"option on the left side of the page.
5. Under the "Policy", select the "Low" firewall option and click on <Apply> to save the setting.

Uncheck the "Filter Multicast" option and click "Save Settings"
