Exchange environment - Adding a reverse proxy - what is needed? RRS feed

  • Question

  • My current setup is a router with port forwarding to Exchange - firewall - Exchange server.

    I will be adding a Skype for Business 2015 Edge server and a reverse proxy, configured in Server 2016, between the Exchange server and router somehow (to be determined).

    What settings in a reverse proxy would be needed to ensure that there will be no disruption to service for Exchange as I'm guessing I will no longer be able to port forward?

    The 2 will be on the same ISP with 1 public IP address.

    Reverse proxy isn't Skype specific. The reason I am adding a reverse proxy is due to Skype. I need to know what is needed to keep Exchange operational.

    I also needed to change the subject as the subject was determined by the original thread subject.

  • Hi Susan_773,

    In fact, there is no feature impact between Skype for Business server/Exchange server with the router. You need only make sure that the request can transfer to the correct server. I also confirmed with the Exchange support engineer. 

    In addition, it is not recommended that the two servers use the same public IP address.

  • My network has 2 ISP's for different services.

    Right now, I can log into Skype for business on a desktop client outside of the building when it is on the same ISP as my Exchange server without an edge server/reverse proxy present.

    When I change the Skype server to use the other ISP, I lose that ability to log in off site. Public DNS is changed. This ISP has a device between my modem and router used for our VoIP traffic and uses the public IP for itself.

    What is needed to get Skype to work on the 2nd ISP so I don't need to purchase another IP address?

  • Hi Susan_773,

    What is the device between the modem and router? It seems the VoIP traffic do some settings in the ISP which have impact on the Skype for Business server.

    The network adapter of each server in Skype for Business server topology must support as least 1 gigabit per seconds (Gbps). In general, you should connect all server roles within the Skype for Business Server topology using a low latency and high bandwidth local area network (LAN).

    You can refer to the network requirements for Skype for Business as the following link: https://docs.microsoft.com/en-us/skypeforbusiness/plan-your-deployment/network-requirements/network-requirements.

    Question 2. My network has 2 ISP's for different services.

    Right now, I can log into Skype for business on a desktop client outside of the building when it is on the same ISP as my Exchange server without an edge server/reverse proxy present.

    When I change the Skype server to use the other ISP, I lose that ability to log in off site. Public DNS is changed. This ISP has a device between my modem and router used for our VoIP traffic and uses the public IP for itself.
