Can't get OWA to work on Essentials 2012 R2 with Exchange 2013 on second server 2012 R2 std.

I have previously with success setup a working solution with server 2012 essentials, and a second server 2012 std. with exchange 2013, I did it following this guide: http://technet.microsoft.com/en-us/library/jj200172.aspx

Unfortunately I lost the server due to a cooling error which led to an un-repairable essentials 2012, since this was a new setup and also a test setup I didn't have any working backup solution setup at the time...tsk.tsk.

Since I had to make a complete do over I chose to try out the new R2 server editions, and set it up following the same guide, when it came to this part:

#

• Copy the SSL certificate file for Exchange Server to the server that is running Windows Server 2012 Essentials. The certificate file must contain the private key, and it must be in the PFX file format.

  Note
  If you are using a self-issued certificate, follow the instruction in the Exchange Server article Export an Exchange Certificate to export the certificate.

  Open a command window as an administrator, and then open the %ProgramFiles%\Windows Server\Bin directory.

• Based on you installation scenario, follow one of these steps to configure ARR:

• If you are performing a clean setup, run the following command:
  
  ARRConfig config –cert “path to the certificate file” –hostnames “host names for Exchange Server”

I noticed that the version of "Application request routing" had changed to version 3, so obviously I didn't need to dl the 2.5 update.. When I came to the part where I wa instructed to run arrconfig config etc. I noticed that the ARRconfig file no longer where placed where the setup guide indicated, I then went ahead and tried som manual configuration regarding certificates and such. In the end I have a working solution where Exchange and OWA is working locally but OWA isn't working outside my local domain, the link get's placed in the RWA and is indicating the correct link for the exchange server www.remote.clinten.dk I have a certificate which include to separate domain names aforementioned and remote.clinten.dk and I get no errors indicating certificate errors, when I try to connect to www.remote.clinten.dk/owa from outside I get a 404 error, and when I connect to www.remote.clinten.dk I get the RWA login screen for the essentials RWA. Obviously I need to set up something in ISS probably in the url rewrite section, but I can't seem to find the right setting.. Can someone help with this?

Btw. I have found the missing arrconfig file in c:\windows\system32\essentials" and tried to run the command as described in the guide "ARRConfig config –cert “path to the certificate file” –hostnames “host names for Exchange Server”" but it doesn't seem to work, it just prompts with a guide for using the arrconfig command and examples of correct use, I also tried removing the "" from the guide, like this "ARRConfig config –cert path to the certificate file–hostnames host names for Exchange Server",when I ran it without the "" It didn't prompt me with anything nor did It indicate any errors, it did not however make my OWA work either..

I am aware that exchange 2013 atm. isn't officially supported on the R2 server, but the exchange works fine inside my domain, and the pop3/smtp also works from outside, since this Is a test environment, using only my own private domain and not a company domain I figured it would be ok to run the risk.. ;)
