  • New Router = No Exchange

    I have a simple exchange server set up at my house. I have one server that is the DC with Exchange and a webserver running as VM's. I purchased a new router that has a different default gateway. The old was 192.168.1.1, the new is 192.168.2.1. I reconfigured all of the servers' IP addresses and opened the same ports that I had open with the previous router. My web server is running fine, the website is up and FTP is working fine. Both my phone and Outlook can no longer connect to exchange. I suspect it's DNS but I'm looking for advice.

    Re: New Router = No Exchange

    You havent really given enough information. How are you accessing your exchange? Are you accessing it from the WAN or the LAN? Presumably your exchange server is in the same subnet and IP range as the rest of your network? Can you access your Exchange from your LAN? If thats the case then you have a routing issue on your gateway.

      Why did you change the servers to match the router? It should have been the other way round.
      You are not restricted to the router's choice of IP address.

      Although I don't recommend using 192.168.0.x or 192.168.1.x as that will often clash with remote access.

      Any number of things it could be, including the bindings on the IIS web site.

        I am accessing it from the LAN. It is in the same subnet and IP range as the rest of my network. If I got to http://fqdn/oma I get a page cannot be displayed error. When trying to resolve the names in outlook I get the "exchange must be online" error.

          You are right, I should have done it the other way around. But what would replacing the router change? I still have the IP addresses correct and the proper ports forwarded.
