Route Sentry

Route Sentry is specially created for South Africans who want to easily make use of two different ADSL accounts on the same computer at the same time
Most people are put off using such a setup due to the inconvenience of having to manually set up the IP routing tables after each new connection (due to ISPs allocating dynamic IP addresses). Route Sentry makes it easy.
It will monitor your 2 connections and automatically route South African traffic through the "local" account while directing all other traffic through the "international" account.
It will automatically reconnect if either connection is dropped (which at the moment happens at least once every 24 hrs) and keep traffic flowing through the correct connections even if the IP addresses are changed after reconnecting.
It should also be noted that the modem does not have to be directly
connected to your PC as this protocol will work just as well if the modem is
connected to a hub or switch on your network. This makes it possible to share the
modem between different PCs on your network for different simultaneous PPPOE
connections.
Important: You must set the number of lines (WAN endpoints) in the PPPOE protocol
properties to 2 or more otherwise you will get an error that the device is busy
when you try to “dial” the second connection. When testing the connection for the
first time you must select the ‘save password’ option on the “Connect” dialog,
otherwise Route Sentry won’t be able to automatically connect for you.
Warning: If you previously used your ADSL modem in router mode you wouldn’t have
had to worry too much about your PC being vulnerable to internet threats as the
modem itself would have acted as a firewall. Using the modem in “modem/bridge” mode; however, means that your PC will be directly connected to the internet when next
you “dial up”, so making use of a software firewall is highly recommended (such as
the built in Windows XP firewall).
One account has to be used for local access only and the other for international.System requirementsADSL modem
