Remote Web Workplace problem

[Prophet]

I've got an issue with RWW on an SBS 2008 server.

If I connect internall from the LAN I get all the options (Check Email, Internal Websites and Access Computer)

However from the internet I only get Check Email and Internal Website.

I've opened all the ports required on the router and the server has no firewall.

Any ideas?

Yes I've been using IE. I've also tried Chrome with the same result.
