Edge Server for Lync

Hi,

We are getting ready to open up our Lync 2013 installation to our users on the other side of the firewall and I had a quick question that is going to influence how I implement the system.
Looking at articles, I see that I need a server with 2 NICs (one using an internal and the second using an external address).  I was wondering if I can use my firewall to translate an external address and actually either have one or two internal addresses.  Has anyone used their firewall to translate external to internal addresses for a Lync Edge server?  If that is possible, then I will just create a VM (otherwise, I will need to use a physical server).

Thanks,

Allie

Lync fully supports NAT. However the edge server still needs two NICs and they must be on different subnets, even if the externally facing NIC is being NATted.

For example, you can have your external firewall NAT a public address to a private 10.x.x.x address for the external NIC, while the internal NIC is on a private 192.168.x.x subnet.

so as you can see, while your question about mapping public addresses is valid, and the answer is that it indeed can be done, it actually doesn't change the two NIC or separate address space requirements
