DNS Hosts when using dual wan Internet connections
Posted on 2011-10-31
Have a SBS server running Exchange and OWA, Remote Web Workplace and other stuff.
A second internet connection for backup will be added soon and probably a Sonicwall dual unit will be installed.
Having two fixed IPs, the challenge is for all services to failover correctly.
For MX Records, I see no problem. Just add a second one pointing to the the backup IP. I guess this is the only change for SMTP incoming traffic.
But the other hosts (i.e: OWA, REMOTE, etc), how can I make them failover to the second IP?
Thanks in advance.
