Hi, everybody.

I would like to know if an additional public IP address is required exclusively for Synchronizing the Address Book from the Internet with OCS 2007 R2.

We have a small deployment, consolidated Edge server, and are getting an error when connecting from the Internet that the Address Book cannot be synchronized.

I have checked these links:

http://technet.microsoft.com/en-us/library/dd441312(office.13).aspx

I would understand that if we already have an ISA box with a public IP address, a reverse proxy rule can be added and no additional public IP address would be necessary, just use a new FQDN for the Address Book and configure it following:

Could you please advice?

Thank you very much.

Regards,

Mario

Normally this would require a separate IP for the ISA listener used on the Web Publishing rule for this. but if you are not using an Edge server and are already publishing other services on the Front-end (not best practice) then you could use the same IP address, assume there is no port conflict.

Unless you are asking about using the same IP address as what's already configured on your ISA as the external IP, then if you already have SSL (TCP 443) used for something else you'l not be albe to use that IP and must selecta a new one.

Thank you very much, Jeff. That's just the answer I was looking for.

I know this is an OCS community, but I'll give it a chance with a related question (related to public IP provisioning).

If I'm publishing Exchange 2007 with ISA 2006 and have a web listener configured for OWA with forms based authentication, I understand that same listener will allow for basic authentication and therefore can be used for Outlook Anywhere. Now, if I wanted to use integrated authentication for Outlook Anywhere, then I understand I would need an additional public IP address with an additional web listener configured with integrated authentication, for the forms based authentication doesn't support integrated authentication. Is that correct?

Best regards,

Mario
