Access Remote PC

Remote access to your PC from anywhere in the world

Transfer files, run programs, access network resources



If a host computer is located behind a router, you should always connect to the router's IP address, possibly specifying the port number after the router's IP address (e.g. 68.103.23.63:12345). If default port 34012 is used by Remote PC Server on the host computer, the port number may be omitted (just 68.103.23.63). Other port numbers must be specified. For information on how to find your router's IP address, see your router's documentation.

There are two types of routers:
  1. Routers that let you specify both external and internal ports. Packets that arrive to the router at port X are forwarded by the router to port Y at IP address N.
  2. Routers that let you specify a single port number. This router type cannot forward between different ports. Packets that arrive to the router at port X are forwarded by the router to the same port X at another IP address N.
You configure router by specifying X, Y, and N.

For example, Windows XP has a built-in software router that lets you specify routes for a dial-up connection:
  • Internal IP address
  • External port number
  • Internal port number
That is, Windows XP is capable of forwarding to a different port.

Windows 2000, on the other hand, lets you specify only:
  • Internal IP address
  • Port number
That is, Windows 2000 does not let you differentiate between external and internal ports.

This example shows only software routing for a dial up connection as it is implemented in Windows 2000 and XP. There are hardware routers (e.g. LinkSys) of both types.


How-to guide for configuring access to computers located behind a router.

1. A single computer located behind a router:

Routers of type 1: Add a single record to port forwarding table:
  • Internal IP address: specify IP address of the computer (shown on the LAN page of Remote PC Server window)
  • External port: 34012
  • Internal port: 34012
Routers of type 2: Add a single record to port forwarding table:
  • Internal IP address: specify IP address of the computer (shown on the LAN page of Remote PC Server window)
  • Port: 34012


Usage: to connect to the computer, connect to IP of the router (e.g. 68.103.23.63)

2. Multiple computers located behind a router:

Routers of type 1: Add one record for each computer to the port forwarding table:
  • Internal IP address: specify the IP address of the computer
  • External port: select a different port for each computer (e.g. 10001, 10002, 10003, etc.)
  • Internal port: 34012
Changes to the Access Remote PC program are not required with this type of router.
Routers of type 2: Add one record for each computer to the port forwarding table:
  • Internal IP address: specify the IP address of the computer
  • Port: select a different port for each computer (e.g. 10001, 10002, 10003, etc.)
Change Remote PC Server port on each computer to the selected port. For example, on computer that was assigned port 10001 in the routers table, Remote PC Server port must be changed to 10001. Remote PC Server port can be changed on the LAN page of the Remote PC Server window.


Usage: if IP of the router is 68.103.23.63, to connect to a computer that was assigned port 10001, connect to 68.103.23.63:10001.
