The port forwarding rules set up via the UPnP Gateway are temporary. The list of 
configured UPnP port forwarding rules is cleared should the SG unit be power cycled, or 
should the internal or external interface become unavailable. 
The UPnP Gateway is intended for transitory application port forwarding, such as those 
established by some versions of Microsoft Messenger for file transfers. For long term 
port forwarding, we recommend configuring the necessary rules via the Destination NAT 
features in Packet Filtering. 
Should there be a conflict, packet filtering and NAT rules have priority over UPnP rules. 
Configuring UPnP rules from Windows XP 
Once UPnP is running on the SG unit, you may configure UPnP port forwarding rules 
from a local Windows XP PC. 
Ensure the Windows PC’s Default gateway is set to the SG unit’s UPnP Internal 
interface. 
After 10 to 15 seconds, a new connection named Internet Connection appears in the 
Windows PC’s Network Connections folder. 
Open Internet Connection, click Settings then Add.
