Installing certificates on ISA Server for Bridging Tab

Hi all,

  Here is my problem.  I am trying to configured a web publishing rule to terminate http at the ISA server and then start an SSL connection to the webserver.  (in my opinion its a little silly but this is what the customer wants.  He is publishing his OWA server on his site using SSL, cannot see the point saying e-mail is sent un-encrypted anyway !).

  I have installed the Certificate in the Local Computer-->Personal-->Certificates and this can be listed in the Incoming Listener (proves the private/public key combinations have been successfully exported).  I have installed the certificate in the Service W3Proxy-->Personal-->Certificates aswell.

  On the Web Publishing rule i have tried to set the Bridging tab to use a certificate to authenticate to the SSL Web server and when i press select i get "There are no certificates configured on this server".

  I am now pulling my hair out and getting no joy.  What have i missed out ?

Thanks in advance

Can you connect to that SSL site internally from any client? If yes, on ISA all you need is to have trusted Root certificate from the CA that your www got cert from. You don't need the cert in Local Computer-->Personal-->Certificates  but in trusted root instead.

Also you are not specifying the cert on ISA, just use ISA as regular client, and redirect http as https, for that no cert is required.

Hi Sebo2000,

  Thanks very much for you reply to this question.  I have posted this on several newsgroups and no-one has bothered to reply.  You can connect to the SSL site (OWA) from inside the network and i have installed two certificates on the server.  One is the certificate for the SSL address and the other is the CA certificate for the Windows 2003 domain.

  I have read the ISA Server.org tutorial regarding the bridging tab (we usually just install it on the listener then bridge through using normal HTTP on the inside), now we need to do something slightly different and allow the connection in through HTTP and then bridge through using SSL.  The tutorial is saying that i need to install the certificate (website cert) in the Webproxy service so i can then select it through the Bridging tab.  Is this not the case then ?

  Thanks in advance for your help

Hi again  Sebo2000,

  I have just done some testing without sepecifying a cert on the bridging tab and it does work.  Not too sure what that is for but nevermind :)

If you need bridging end to end SSL, you will need 1 public cert on the external lisner with the fqdn name that users are using domain.com and also trusted root cert to your local CA, this way you will have public SSL on on the isa new SSL will be established with your intenral OWA and internal Cert. But most 0of the people don't need internal SSL so SSL ends on ISA
