Lync 2013 using iApp - Reverse Proxy Issues
Using iApp f5.microsoft_lync_server_2010_2013.v1.2.0 with a new Lync 2013 deployment.
Having some problems getting internal mobile clients working. We are currently testing with the Microsoft Lync Analyzer tool as well as Ipads and a Windows 8 tablet.
We have 2 F5. One is in our DMZ the other is internal. On the DMZ f5 we have set it up as the Reverse Proxy and given it an IP of 10.10.10.244. It has the cert with all the correct SANs. In the next section of the iApp it asks for the IP address of the internal side of the Reverse Proxy along with certs and we have it set up with 10.10.20.60 and the correct certs. This is where things get a little confusing for me. The instruction in the iApp ask: What is the port 443 virtual server IP address that forwards traffic to the Front End Servers?
I cant telnet to 10.10.20.60 over port 443, but I think that's expected because it should be using 4443 correct? It is doing a reverse proxy from 443 to 4443. So is the wording wrong in the iApp instruction or am I reading it wrong?
The error from the testing tool is: *An error occurred while sending the request. The underlying connection was closed: An unexpected error occurred on a receive. Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. *
That leads me to believe that the Reverse Proxy External IP is accepting the connection, trying to send it on to its next hop, the internal IP and then failing. Possibly a cert issue so I ran tcpdump on the DMZ F5 and I see no attempt of it trying to traffic back out.
Thoughts?
