We have a small company that has several remote sites. We use Terminal Services to connect thru the internet to the server. Users start a desktop terminal services icon that points to mycompany.com.
I have a SonicWall TZ170. I have two internet providers, ISPA and ISPB. I have a static ip from each provider: a.a.a.a and b.b.b.b. I have set provider ISPA up as the primary provider.
I have an A record at my hosting site that points to a.a.a.a. I also want the hosting site to point to b.b.b.b. Then, when users startup the TS icon, if ISPA is down, they will go to ISPB.
My first question is, am I handling this in the correct manner? If so, can I have two A records that point to different static IP's? If not, what is the best way to accomplish this task?
