  • reverse proxy for Exchange

    Jul 12, 2016 02:58 PM|Chris m|LINK

    I have 2 servers, 1 windows 2012 r2 Essentials and 1 Windows 2012 r2 datacenter with exchange 2013 installed.

    i have remote web access setup using a microsoft domain (xxx.remotewebaccess.com).

    the remotewebaccess domain is configured on the essentials server and i have in the past had a reverse proxy setup which passed the exchange 'stuff' to the exchange server and left access to the remote web access 'stuff' on the essentials server.

    how ever i recently tried office 365 for my email and deleted the config (i know i should of backed it up) and now im wanting to revert back i cant seem to get it to work again, i have tried all the sites i have tried in the past and nothing seems to work does anyone know how i managed to do it orriginally or how i can do it now?

    when I said tried office 365 I mean I used exchange online so no I didn't install it on the datacentre server, the datacentre still have exchange setup and working its just not been used.

     and when I say I cant get it working, this is what my problem is.

    originally I hade iis setup on the essentials server which was internet facing, using ARR, if a user was to type https://xxxx.remotewebaccess.com/remote they were taken to the remote web access page on the essentials server, if the typed https://xxx.remotewebaccess.com/owa or /ecp ect. they were taken to the exchange login page on the datacentre server.

    I have managed to get the exchange side setup  (https://xxx.remotewebaccess.com/owa ect.) but there is no access to https://xxx.remotewebaccess.com/remote I just get a 404 error.

    there is no other error messages and nothing in the logs, I do know it is possible as I have had it working before I just cant remember how!

    Hi,

    Please take a loot at the following link, check if you missed some steps to setup reverse proxy.

    http://www.iis.net/learn/extensions/url-rewrite-module/reverse-proxy-with-url-rewrite-v2-and-application-request-routing

    404 error mean that the path you request doesn't exist, please check if you have related file in physical path.

    You can Failed Request Tracing to get more error information about this.

    Thanks for replying,

    I forgot to post yesterday, I resolved the problem by adding to the rewrite rules, I just added rules that said the {REQUEST_URI} did not match then added all the virtual directories on the default site in iis e.g. /remote/*

    Since I did that the exchange server works as expected and so does the remote Web access.
