I'm trying to find out if it is possible to use The Dude to check if our internet connection is going via a particular route
Our internet connection is provided using a microwave dish (we're in the middle of no where and this is the only method of getting anything like a reasonable speed connection) and has an automatic ADSL fail over in the event of problems with the dish
Our ISP is pretty good when it comes to contacting us if they notice we are running on the backup connection but that means we are being reactive to any connection problems and it would be nice if we were able to detect when we've dropped onto the backup connection ourselves
Having spoken to our ISP the only method we have of identifying whether we are on our primary or backup connection is to do a tracert to an external address (any external address) and check the IP address of the second hop, if it ends in .10 we're on the primary whilst .140 is the backup
Is there anyway to get The Dude to monitor our connection and notify us if it sees that we are going out via the .140 route?
