Setting up the network
Note: These instructions are likely to apply irrespective of which VNC-compatible Server technology you are using.
If you are connecting over the Internet (via Wi-Fi or over a 3G/GPRS/EDGE mobile data network), the computer you want to control will likely be protected by at least one firewall and router. If this is the case, you must:
- Configure each firewall to allow network communications through to the port on which the VNC-compatible Server is listening. The instructions for this are specific to firewalls; consult the manufacturer's documentation.
If you are using VNC Server and the computer is protected just by Windows Firewall (available with XP and Vista), then it will have been automatically configured to allow communications through to port 5900 when it installed.
- Configure each router to forward network communications to the port on which the VNC-compatible Server is listening. This procedure is known as port forwarding. The instructions for this are specific to routers; consult the manufacturer's documentation, or visit www.portforward.com.
Note: For a more detailed guide to configuring firewalls and routers for Internet connections, see this Knowledge Base article. consult the RealVNC Knowledge Base at http://kb.realvnc.com.
If you are using VNC Server, it listens on port 5900 by default. You can quickly discover on which port it is actually listening, and, if necessary, change that port. Note that Apple Remote Desktop/Remote Management always listens on port 5900. For other VNC-compatible Server technology, consult the manufacturer's documentation.
Providing you are able to configure firewalls and routers, you should be able to connect. Connecting from VNC Viewer »
