Backup internet line
Posted on 2014-10-27
Hi there, im trying to work out the best options and if there are any options i have not thought of for when you have a backup internet line in place.
If you have a on site exchange server and your main internet line goes down, hopefully your backup internet line kicks in, how would/should things like your DNS/MX/A records/external IP addresses be site up on the domain name to allow for email to still be able to hit your exchange server on the backup IP address if your main line and main IP address are down?
I guess this would also apply to if users connect to the server with a VPN
