Automatically configuring router

Starting version 3.4, SynaMan can automatically configure firewall allowing home/novice users to get up and running in minutes without changing anything in their router. This automatic configuration only works if the router supports UPnP and it is enabled.

Some routers use this logo indicating UPnP is supported

Universal Plug and Play, or UPnP, is a set of networking protocols that allows different devices in your home network to seamlessly discover each other and communicate and share data. Think of it as a language that your networking devices use to speak to each other, helping to simplify the process of network configuration. Many popular routers use UPnP, which greatly simplifies the accessing SynaMan from the Internet. Consult your router's documentation if you're uncertain whether it supports the UPnP protocol.

How to enable/disable UPnP

When SynaMan is first installed, the setup wizard prompts the user if UPnP should be enabled. Follow the steps below to enable/disable UPnP after initial setup wizard is complete.
  • Login as admin to SynaMan's web interface
  • Click Configuration
  • Select the tab for HTTP Configuration
  • Check the box for Enable UPnP

When NOT to use UPnP

If you are an experience user and know how to configure firewalls, considering disabling UPnP in SynaMan and manually configure the router's port forwarding. The goal of using UPnP is to quickly get you up and running with SynaMan and allow users on the Internet to connect. However, there are certain down-sides of using UPnP. For example:

  • If you have more than one machines running SynaMan, firewall will get confused and one of the server won't work.
  • Depending upon the router, you may lose connectivity if the when the router is rebooted.
