RPC over https for Outlook - Single Server Implementation

I would like to setup my external customers (on the internet) to use Outlook using RPC over https.  I would like to do the single exhange server deployment.  I no perimeter network, no ISA server, or front end proxy server.  We have one firewall.

Is it reasonable to use our Sonicwall to filter the RPC traffic from the outside to our exchange server.  Essentially, I would have to open up ports 6001, 6002, and 6004 (443 is already open)?

client --> sonicwall --> exchange server with rpc over http (configured for https, forced 128bit encryption)

The first time I did this I used this walk through;
http://www.petri.co.il/configure_rpc_over_https_on_a_single_server.htm

The only suggestion I would make is that you purchase a certificate from Network solutions, GoDaddy or somewhere else.  The self made certificates can cause more problems then what there worth.

If this is a SBS server then you can use a wizard to set this up very easily (even with a self made certificate).

you only need to open 443 to the outside world - the other ports you mention are internal use only.

Thank you for your response.  I have a 3rd party cert in place for that server already, so it will be a pretty simple process once I feel good about the firewall aspects.

I feel like more research is needed.  The perimeter network accepts incoming traffic and re-routes it specifically and securely inside.

You don't think it's too much of a risk to take out the middle man?  I would be exposing the exchange ports to the outside world.  Having the ISA server would allow us simply to expose those ports via that server only.

Since the middle man is forwarding all the ports anyway then the additional risk is minimal, assuming your firewall is configured properly.
