Hello, I am not 100% sure regarding Lync Server, but I am a Web host and as long as you have DNS configured you can resolve as many FQDN to 1 IP address.

for an example:

Website 1: IP: 222.000.25.250
                  FQDN: domainname.com, www.domainname.com, mail.domainname.com, etc.
SQL:          IP: 222.000.25.250
                  FQDN: sql.domainname.com,portnumber

I hope this helps.

Do you intend to have the Lync services available on the internet?? or is it only on the intranet?

                  FQDN: domainname.com, www.domainname.com, mail.domainname.com, etc.

Website 4: IP: 222.000.25.250
                  FQDN: domainname.com, www.domainname.com, mail.domainname.com, etc.

You'll need a unique IP for each host as you'll have a port conflict over 443/80.  You can't publish separate Front End pools on the same external IP because of this.

I very well may be barking up the wrong tree, but if simple URLs are utilized would you not imagine that a single 'Public IP' can be used with local IPs for resolving the reverse proxy, NLB etc..

http://technet.microsoft.com/en-us/library/gg398287.aspx

Since an IP address resolves to a FQDN and that same name and IP can be used with both protocols i.e http:80/https:443 with out conflict in most situations.

From my prospective (I am not experienced with Lync but proficient with Exchange and web hosting) I can not see why you cannot use the single IP address for the public web service as long as you have your host-name (FQDN) bindings setup and DNS configured.

I am not familiar with your hardware setup, but is it safe to assume that you have a single public IP address administered by your ISP, and you are port-forwarding requests to internal IP address?

Hello Jeff,

I understand why we cannot use same ip for 2 hosts.

I need to know when we have 2 pools with lync 2013 and Lync 2010. We use Meeting co-existence between two pools. So we should publish both Web Services urls to the internet.

So if we use IIS ARR, do we need to use 2 Server Farms ? Please give us some idea.

Technically you can use a single IP with a single listener for multiple rules, but it's nothing something that the Lync Product team has tested or supports for ISA/TMG nor IIS ARR as a reverse proxy,

Se the following scenario is possible, and others have successfully deployed environments in this way.

The officially supported route though is to use a dedicated external IP for each internal server or pool which is being published.  So if you are publishing 2 internal servers you need 2 rules, 2 listeners, and 2 public IP addresses.

hello,

thanks for the update.

My question is, If we have 2 Public Ips, can we do this with 2 Server Farms  in IIS ARR ?
