I am presently looking to help a client with configuration on a ASA5510 for the addition of a internet connection to act as a backup connection in the case the cable goes down. I am new to the high availability arena with the ASA and I would like to know if anyone can help guide me to a document that will help me get the configuration going correctly.
We have a couple of cable modems and when the service company goes down or has issues, it is troublesome to get it repaired in time without limited or no access to the internet. My plan is to recommend a Wireless 4G network connection as a backup but I need to be able to configure the ASA to look for the connection in the event the Cable modem bank goes offline.
Please let me know if you have any recommendations for how this can be done so I can get started with some ideas for the present contact on this issue.
