Sharepoint integration with EP7..

Hi,

We have an EP7 portal which will be made available on the internet (Externally facing).

The EP7 has a home page with many links to the documents on sharepoint. Also, there are links to some .aspx pages running on sharepoint. We need to make all the documents and webpages available on the EP7 so that it is accessible externally. The sharepoint server is available only within the network.

How do we achieve this ? Is an EP <--> sharepoint integration sufficient? or do we need to look at using federation of Portal between EP & Sharepoint to get the webcontent?

Thanks for all suggetions!!
