A\V边缘服务器的Internal NIC能用NAT吗？

Is it possible to use NAT on the internal NIC on the A/V Edge Server?

这里讨论A\V边缘服务器能不能用NAT的问题，OCS 2007边缘服务器本身就是个麻烦事。

I know that the external NIC must be public routable and not NAT`ed.

Is it possible to use NAT on the internal NIC on the A/V Edge Server?

I have NAT on my Internal NIC, but when I run Valtidate A/V server on my Front End server it failes because he tries to access the Edge server ordinary internal NIC address instead of the NAT address.

In the internal DNS I have created an a record thats point to the NAT adresse, and I can sucessfully run telnet against the NAT address on 5062 when I use FQDN

Any clue why the validation not use the NAT address?

YES, the internal interface can use a private IP address; that is recommended configuration as well.  Only the interface assigned to the A/V Edge Service requires a public IP address.

Here is what is wriiten in the Microsoft Office Communications Server 2007 Planning Guide, page 95:

Note

To conform to the requirement of a publicly routable IP address of the A/V Edge Server, the external firewall of the perimeter network must not act as a NAT (Network Address Translator) for this IP address.

Additionally, the internal firewall must not act as a NAT for the internal IP address of the A/V Edge Server. The internal IP address of the A/V Edge Server must be fully routable from the internal network to the internal IP address of the A/V Edge Server.
