Access Internal Website from External Website
We already have a public ip address which points to e.g. www.ourdomain.ac.uk. We don't want to purchase additional public ip addresses as:
1) we've been told we don't have to by our sharepoint engineers
2) we have to purchase them from our supplier in blocks of a certain number
We have created internal subdomains in the example sharepoint.ourdomain.ac.uk and staff.ourdomain.ac.uk. Both of the subdomains point to websites on internal webservers. The domain www.ourdomain.ac.uk points to our webserver on the dmz.
Is it possible, using host headers and DNS to allow the subdomains to be accessible from the internet without purchasing additional public ip's, and if so how do we go about implementing the solution?
We use Microsoft servers running the latest version of IIS.
