Lync 2013 FE & Edge DNS Settings

Back again. My issue is simple to a point, I am trying to find the correct DNS settings for my setup. The setup is fairly simple. I have a Lync (Front End) 2013 sitting on Windows 2012R2 Standard on the domain. I also have an Lync Edge Server 2013 on a Windows 2012R2 Standard not on the domain. We host our own DNS servers. When I started out everyone liked the Lync and it worked great inside our network. Now of course I need to make it work outside.

For our inside DNS we have DNS for both local and outside (abc.local and abc.org)  and for our public DNS we have abc.org. What I would like greatly is to figure out the correct DNS settings for everything. We plan on using IMing, pc2pc calling, Conference Calls and presentations. Basically the basic setup as its setup inside. My Edge Server does not talk to the outside world yet because I still need to configure the router but right now my Lync does not work right on my network inside.

I have looked up DNS settings and I can never seem to find any that match. It should be easy to say if I am running a service , then I need a certain type of record pointing to either an ip address or host, what port to clarify (if at all) and which network to put it on (i.e. abc.org/public DNS or abc.org/local Inside DNS. This wouldn't be such an issue if everyone didn't have a different issue. Such as I have three users and the Lync works fine, I have others that pop up a DNS error, others that say the server is temp. unavailable and yet still users it just hangs signing in, never pops up an error code or anything. All this on the same network. Any help would be appreciated. The more simple the better.

Where I would point my outside NIC (NAT'd) default gateway on my Edge server would be a bonus.

you need following external DNS records:

meet.abc.org
dialin.abc.org
lyncdiscover.abc.org
lyncext.abc.org (Lync external web url)  
All of those point to reverse proxy Public IP. remeber public certificate on reverse proxy

sip.abc.org (or similar, like im.abc.org, access.abc.org) - point to 1 public IP on Edge (either directly or NAT'ed) - for remote access. Remember to put dns-name in certificate
webconf.abc.org - point to another public IP on Edge (either directly or NAT'ed). DNS name in certificate
av.abc.org - point to another Public IP on Edge (either directly or NAT'ed). Not needed in certificate

following service records:
_sip._tls.ab.org - point to - sip.abc.org (port 443)
_sipfederationtls._tcp.abc.org - point to sip.abc.org (port 443)

Can our 2 Public DNS "act" as a reverse proxy or would it be better to build a proxy server in my current configuration?

Jakob DigranesSenior ConsultantCommented:
you'd need some sort of reverse proxy, either Microsoft TMG, Citrix Netscaler or Windows 2012 reverse proxy --- or similar

I understand that you feel its answered. I need a little more to move on. I now have the Lync (FE Server), Edge and Reverse Proxy Server I need to configure. We host our own DNS. Once I get ready these settings will have to be clarified once my setup is ready which I am sure many will appreciate.

I can elaborate more now that I am further into this. The more research I do the more I do not get clear answers. Now that I have 3 servers for Lync ( Front End, Edge and Reverse Proxy) I cant seem to find the right setup for having all three in place. Not only is it unclear now where to put the DNS settings it would seem settings where to point each NIC to which other servers NIC's and or outside settings. Also now that I have a reverse proxy with the other 2 servers which IP's (NIC's) do I point the Server Farm to is IIS Manager? Any help would be useful.

I will accept this as an answer as I asked it. My scenario has become more complex and I hope I will get more help as I open a new question. Thank you Jakob for your input.
