MS CRM 4 - External access - IFD - DNS - need more detail

I have upgraded from v3 to V4 on our SBS 2003 R2 network. I read the MS IFD
docs and installed and ran the IFD tool. I followed as best I could some
examples posted here but when trying to open the web client remotely I get
"Internet Explorer cannot display the webpage". The Outlook client and web
work fine on our internal network.

SBS RWW works fine from the outside.

We are using dyndns for this site so I'm not sure how DNS might be
configured in this case. I don't understand how the subdomain used when
connecting from outside relates to the DNS server on the SBS server. I
created a forward lookup zone alias (CNAME) but don't see how that helps
reach the site from outside

I'm also what if a port need to open on our firewall. Right now I don't have
port 80 open. Is it customary to use 2525 ? I saw that port in an example in
the documentation.

If the IFD tool has been run is it still necessary to modify permissions or
edit the registry?

The IFD doc recommends using fiddler to create test pages and place them in
the root of the CRMWeb folder. Is that done using the sandbox feature?

Thanks

I opened port 2525 on our firewall and forwarded it to the CRM server. I
assigned externaldomain.dyndns.org:2525 (no subdomain) in the IFD App Root
Domain and IFD SDK Root Domain. I'm using HTTP for the IFD Domain Scheme.

Perhaps this can't be done with a yourdomainname.dyndns.org dns name? In
that case could we use the external ip address?.

Perhaps the problem is that the dyndns name requires a subdomain entry such
as test.dyndns.org?

Thanks,

One more question. After applying the settings in IFD tool where I can check
what changes it has made. I looked in the registry for MSCRM and web.config
and saw not changes.

I got remote access working - I noticed the bottom example in the Microsoft
supplied guide to IFD used the same port for external facing and internal.
That made sense to me - I didn't see how Dynamics CRM system would somehow
translate the port. I think my problem was that I was reading Phil
Richardson's post about how to switch back and forth between IFD and On
Premise. His example's used two different ports. I still don't understand
what he is explaining in his 3 part series on IFD. I put my
dyndnshostname.dyndns.org:5555 in the IFD App Root Domain and IFD SDK Root
Domain. Then I put the mscrmservername:5555 in the AD App Root Domain and AD
SDK Root Domain
