Confi guring all outbound communications through an OCS
2007 edge server will effectively minimize half of the responsibility of the LCS 2005 proxy.
The process of redirecting internal LCS 2005 server communications through a new OCS
2007 edge server is as follows:
1. While logged on to an internal LCS 2005 server, click Start | All Programs |
Administrative Tools | Live Communications Server 2005.
2. Expand the LCS 2005 tree.
3. Right-click the forest node, and then click Properties.
4. On the Access Proxy tab, click Add.
5. Enter the FQDN of your new OCS 2007 edge server, and then click OK.
6. The Live Communications Server Global Properties Access Proxy tab should
look something like Figure 11.7. Click OK to accept the confi guration change.

Redirecting Inbound
Traffi c to the New Edge Server
With an OCS 2007 edge server now handling outbound traffi c successfully, the next step is
to redirect inbound traffi c through this new OCS 2007 edge server as well. Redirecting inbound
traffi c is a little trickier because the rerouting is done through a modifi cation of public DNS
records. Again, though, if the new OCS 2007 edge server has the same server name and IP
address of the old LCS 2005 proxy server, the minute the new OCS 2007 edge server is
back on the network, communications will go to this new edge server instead of to the old
access proxy server.
As long as the external FQDN is set to route inbound traffi c through the new OCS 2007
edge server, the new server should take the connections and route the communications to
the internal servers for delivery.
