What you want to implement is called an Extranet:

An extranet is a private network that uses Internet protocols, network connectivity, and possibly the public telecommunication system to securely share part of an organization's information or operations with suppliers, vendors, partners, customers or other businesses.

If the intranet portal contains sensitive information then I would encrypt it using SSL and the publish it on the web, we have done this with may of our intranet site, e.g. time registration system and TFS. If you want only certain users have access that site, you could configure certificates and then let these users install the certificate on their machines.
