Setting Up The Router As A Virtual Server - Gigaset SE105 Owner's Manual

Setting up the router as a virtual server

If you want to offer files or Web services that are on a PC in your local network to other
Internet users, set the PC up as a server (e. g. as FTP or HTTP server). However the
router's NAT function does not normally allow "external" access to PCs on the local
network. To make services available on the Internet from local PCs, you have to set up
the router as a virtual server.
Externally the router takes on the role of the server. It receives the requests of remote
users under its public IP address and automatically redirects them to the local PCs. The
private IP addresses of the servers on the local network remain protected.
Internet services are addressed via defined port numbers. The router needs a mapping
table of the port numbers to redirect the service requests to the server that actually
makes the service available.
You have to set up this mapping table.
You will find a detailed example of how to set up the router as a virtual
i
server in "Practical Tips and Configuration Examples" on the supplied CD.
