Microsoft Skype for Business Server 2015

Hi Folks.

 

I was wondering if any of you could help me with an issue that I'm having on a Skype deployment using iApp. I've searched a lot about it but couldn't find what I am doing wrong here.

 

I am trying to deploy Skype Server using template, but I'm having problems to connect to the Edge Servers using mobile devices. While trying to login from a mobile device I receive a "Can't connect to server" error, but if I use a Windows device with skype client installed it works fine.

 

Looking at tcpdumps on BIG-IP I can see the client trying to connect to AV Virtual Server on port 443 and receiving a reset after some time trying to connect to the server.

 

I am using automap for all the virtual servers, since BIG-IP is not the route for the skype servers. I'm also deploying the virtual servers behind a firewall NAT. On my Edge Server topology I'm using a single IP on the External Interface to handle all the three services on it. I've used the following guide to deploy the environment: https://devcentral.f5.com/s/articles/the-hopefully-definitive-guide-to-load-balancing-lync-edge-servers-with-a-hardware-load-balancer

 

During the iApp configuration I've answered Yes only to deploy Edge Services to the External Interface and to deploy the Reverse Proxy.

 

Has anyone seen a problem like this?

 

Thanks in advance.
