SBS 2008: Dynamic Public IP

Given: The company has Dynamic public IP. (ISP blocks standard protocol ports, ie 25, etc.)

ok. i just want to be sure of what iam thinking.

in IAMW (Internet Address Management Wizard)
- Select the “Set up your Internet address” task.
- Select “I already have a domain name that I want to use”.  Click 'Next' and domain management section wizard pops up and there are 2 options to choose:
> I want the server to manage the domain name for me.
> I want to manage the domain myself

if i select "I want the server to manage the domain name for me." does this mean that SBS 2008  DDNS service will manage to update its public DNS record given that the company has Dynamic Public IP and to transfer the name servers for this domain to supported DNS hosting comapny like Godaddy?

and the "I want to manage the domain myself" given that the company has Dynamic IP does this mean that they have to purchase like DynDNS services (mailhop outbound/relay) and client updater to automatically update the public DNS records?

The existing DNS right now is hosted by this DNS NS

please help. thank you

You would normally go for the second option"I will manage the domain name myself" then you would configure your MX records etc in the external DNS provider.

If you have a dynamic IP then your best bet is to sign up to a 3rd party service so you can collect your mail from them via POP3 and then send your mail to them via SMTP and they will relay it for you.

Otherwise when you send mail a lot of providers will reject your mail.

Thank you for your response. Does RWW will work in Dynamic IP? will the users outside the network can access the RWW?
Glen KnightCommented:
If you sign up to a service like DynDNS then yes.

You really should look at getting business class broadband though and all these problems will be elminated.
