You may administer the WinRoute Pro Engine from any computer in the world as long as there is a TCP/IP connection in place. The administration is secure (encrypted) and controlled via user name and password.
In order to administer a WinRoute computer from outside the LAN (from the Internet) Port Mapping must be set on the WinRoute computer (assuming you're using NAT and the host computer isn't excluded). With NAT enabled on the interface linking to the Internet (necessary for Internet sharing) your entire network including WinRoute computer is fully protected and therefore no one has the access to it.
To set Port Mapping for remote administration go to menu Settings=>Advanced=>Port Mapping, press add and set:
Protocol: TCP/UDP
Listen IP: <unspecified> (recommended) or the IP address of the Interface.
Listen Port: 44333
Destination IP: The IP address of the interface linking the WinRoute computer to the local network (private class IP address)
Destination Port: 44333
Allow access only from: If checked you may further limit the access to the WinRoute Engine. You have to predefine IP addresses allowed to access WinRoute Engine from the Internet in menu Settings=>Advanced=>Address Groups. You may group together separate IP addresses, ranges of IP addresses and networks.
See examples for more details about Port Mapping. If you have everything set accordingly just run WinRoute Administration program from any computer and enter the IP address of the computer running WinRoute and also the user name and password used for administration at that computer. See User configuration for further details regarding User name and password policy for administration.
