The purpose of this script is to provide a solution for loss of service from ISP providers. The idea is for a topology where there are two different ISP providers, one of them provides a static IP and the other provides a dynamic IP address.

It is important to clarify that DNS should be usable from either ISP connection. This is because each ISP has its own DNS service. If a connection is lost it is likely that ISP 2 will not be able to connect to the DNS at ISP 1 and DNS requests will not be allowed to be resolved. The solution to this is to use a public DNS service such as OpenDNS.

How it works:
The solution is composed of 4 netwatch tests.

The first (test 1) checks www.google.com, if for some reason this address stops responding to pings then it enables test2 and test1 disables itself.

Test2 pings www.yahoo.com, if the result is UP it enables test1 and test2 disables itself. If the result is "DOWN", test2 looks for the address of the gateway of the ISP on a dynamic IP and configures that address as a static route, followed by disabling the static route of the ISP on a static IP and enabling the dynamic IP route previously mentioned. It then sends an alert e-mail and enables test3 (for the new dynamic ISP) and test2 disables itself.

Test 3 and test4 do the same thing as test1 and test2 respectively. Only in this case, test4 would release the dynamic ISP and re-enable the static ISP.
