You will require Certificate to access OCS from outside along with natted IP.

Refer part 4.

I'm not an expert on this subject, but I am deploying my own OCS system at the moment and maybe I can help you out a bit.

Are you looking at implementing an Access Edge server as well? Or do you want people to access your current server?

Do you wish to enable auto-discovery for the Communicator client for external users? If so, what SIP domain did you choose? Private AD domain name?

Have you read through any particular documentation sets on the subject?

A couple of good links:

Question:  How do your existing 10 external users access your environment?  Our external/home currently VPN in first, no additional setup required to access via VPN connection.

Edge will add security which will filter the traffic flow from inside out & vice versa.

Check the Document for Edge Server Deployment.

It has all the details for Deploying the Edge Server for Remote Connectivity.

Edge Server is always required for External Access wheter you use Standard or Enterprise Edition. Front End Server servers the connection for only internal Clients.

For Clients to connect to OCS Outside the Domain Edge Server is required.

The Edge Server should be installed on a Work Station. That is the recommended way. Do not install any other Server Roles on the Front End Server. It is not recommended and would end up having Issues.

This includes Exchange Server as Well.

For best practices, edge role has to be installed on DMZ for providing secure server access which wil travel through Edge role for external access.

The edge role act as a filter for OCS server holding other roles.

AK Reddy,

You need a dedicated server, with two or more network adapters. On this server, do NOT join to the domain, but leave in WORKGROUP. You will need to have one network adapter on the LAN, one directly connected to the internet.

Also, you need some "Reverse Proxy" server such as Microsoft ISA Server 2006/Forefront TMG installed in order to publish some of the OCS standard/pool IIS sites.

Plus you will need a combination of SSL certificates on the Reverse Proxy, and also on the EDGE server's WAN interface.

It is a somewhat complicated deployment, as the certificates are "tricky". But you can get it done if you are going to have these resources in place. If you do, continue the thread and people can get you up and running. Also to make the certificate part easier, you can use an internal CA server (your domain controller, etc) and manually configure the remote workstations, rather than purchase SSL certificates before you know which ones work.
