2013 Lync Setup for Outside Access

I have a 2013 Lync Server I have built. Everything works great inside the office. I have been asked to make the Lync work for outside access so people can work from home and be able to use all the options. I can't seem to find any good instructions (video or written) that make sense. We have our own public DNS servers which is making the configuration a little tricky where to point everything.

The setup: The Lync Server is installed on a 2012R2 Server and is a VM. All roles are installed on this machine even the Edge service (not sure if this correct considering 2010 best practices) and only serves 30 people. I have ran the MS connectivity analyzer and it get as far as seeing the autodiscover but nothing else.

I'm not sure if its just my DNS settings. The public DNS servers hold our .org domain on a separate location. Our inside network has DNS for our .org and .local.  It would be nice to simply know what A and SRV records need to be on which location pointing where they need to be and if by making the Lync server an all in one is a wrong decision.

You need a separate edge server. The topology builder won't even allow you to build a valid topology with the edge and FE on the same server, and therefore the installer won't install all the necessary services. There is no shortcut; external access is a two server solution minimum.

I will build one tonight. Can I build the Edge Server in the same location? I'm pretty sure you cant put it on the domain. I will have to figure out DNS still. It was weird that the Topology builder said everything was good.

This article should answering any questions you have about the Edge Server role:

It should not be domain joined and should be in a perimeter network, not on your internal network.

You can put it on the domain, but there is a difference between "can" and "should." Technet actually has pretty good guidance on topologies.

Thank you for all the help. My next step will be a reverse proxy server. Unfortunately at this time I am stuck at the settings of the previous admin who set the Cisco ASA. At this time I am yet to test settings outside the network due to network configurations. I inherited a mess but I will get through it. Thanks all and I might be posting again soon.
