I am looking for the proper way to setup my new Sonicwall 2400 with dual WAN connections to work with Exchange 2003 server. I have my DNS setup like the below example. I think I am doing something wrong here. When I nslookup mail.mydomain.com I get both IPs listed below. How do I properly route incoming mail through my primary ISP and then have the secondary ISP only route mail when failover kicks in. My question is very similar to (http://www.experts-exchange.com/Networking/Misc/Q_21595855.html
). But that didn't really give me the answer I was looking for. What am I missing here? Thanks in advance!
mail.mydomain.com 7200 184.108.40.206 (primary ISP static)
mail.mydomain.com 7200 220.127.116.11 (failover ISP static)
