Hello

I cannot find information if it is possible to create a single Lync 2013 Edge server with a Reverse proxy on the same server?

Would it not be possible to share port 443 with SNI support? That way we could use only one public IP?

Thanks!

Sorry, it doesn't work.  Remember that 443 isn't HTTPS for the Edge.  If you went with the single IP model for the edge, 443 would be used for the A/V role which would be STUN/TURN. 

The edge will always want to listen on 443, it just doesn't work to collocate a reverse proxy.

Would the A/V role not support being hosted on another port? I guess autodiscover will tell the clients to use another port automatically?

That would free up the 443 port?

The internal NIC will also want to listen on 443.  You could try, but it's not supported, not designed this way and just doesn't work well. 

Hi Mobay,

the following solution is not supported: if you give 4 IP to the Internet facing NIC (3 for EDGE + 1 for RP) you can add the RP role to your EDGE server. I've made it with Apache (before the ARR solution became the standards RP for Lync).
It works, but as not supported, if you have some issue you are alone....
About SNI, I'm not sure but 99% it doesn't works.

Thanks for the answers everyone. I am bit confused about the edge role.

Are any of the 3 edge services actual websites that the users will visit through a browser? i. e. the Access Edge service,Web Conferencing Edge service or A/V Edge service?

Because if not, what benefit is there to use 443 over any other port?

They are not HTTPS, they are encrypted. Port 443 is used because it is likely to be opened no matter what firewall you may be behind. Just used for maximum compatibility.
