two broadband connections
user has two modems attached to a Sonicwall TZ 180W. One is a DSL with five static IP address. The other is a cable modem with a dynamic ip. Right now I have the Sonicwall using the cable modem as the main internet connection because it is much faster. The DSL is just there for failover.
The DSL is also being used for its static IP address. A domain name is associated with that IP for remote access to the server and for email.
The DSL modem went out yesterday and the user was unable to contact his email or remote into the server.
The server is running Microsoft SBS 2003.
I would like him to be able to still access it if either one of the connections go down.
I recommended getting a static to dynamic IP address through NoIP or another service. Is this the best option and would this work well, or is there another, better option?

My comment won't work- mx records are bound to an IP.

bryon44035v3:The cable modem had dynamic IP not static.
You can still use DNS failover with a dynamic IP so the user only has to remember one dns name to connect to. Just use DynDns on the cable modem connection and a CNAME in the failover that points to the DynDns name.
Just to be clear there are two issues here
- primary and secondary MX (that's the easy one)
- same DNS name pointing to whichever is the primary connection and failing over to the secondary connection so external remote user only have one dns name to remember.

Thanks for the posts. I called the cable provider and they won't give static IPs at this location, just to clarify.

Thanks for all the help. I think I'm going to just wait and see how the one fixed IP connection does. If it's stable now and doesn't fail, then I'll just leave it. Otherwise I will recommend hosted Exchange or the No-IP option.
Something like this:
-allow email traffic cable
-allow internet traffic cable
-allow email traffic dsl
-allow internet traffic dsl
The logic is that, when the cable modem fails, the dsl will take over. The only kicker with this is that you would have to put email through the cable modem and you would have to have some type of bandwith balancing on your sbs.
