Reverse Proxy (Linux + Apache + Web Mail Redirect)

HCL Domino Domino Forum
1

I am trying to built a reverse proxy so that user from outside can read their email via DWA. I have search the forum and found a lot of question about the problems of building such solution but none about the actual resource it require, hence my questions below

  1. What kind of machine is needed for the reverse proxy ? We have about 1300 users, initially up to 20% will use the proxy and the number may rise up to 80% in 1-2 years time. Can anyone who had implemented this tell me proxy server’s hardware specification ?

  2. Have anyone tried Webmail Redirect across mutilple mail server. We are thinking of building a portal and redirecting all request from the proxy server to this portal. Obviousbly the Webmail Redirect will be placed on the portal. I am a bit worried about how the authentication and mail file redirection will work among multiple server. Have anyone tried building these kind of systems (reverse proxy + mail file redirection on multiple server) ?

Any help will be appreciated

Hi Tinus,

I’m not sure on 1 as I’m not running a big shop like that.

On 2 I may be able to help, Ive just implemented an apache reverse proxy using SSL in front of a Domino server running IWAREDIR. Banged my head against a wall a bit as the redirect had me stumped but (using iwaredir anyways!) part of the key seemed to be ensuring that the redirect returned the same fqdn as the proxy. I can post more details if you want.

Cheers

Thanks for the offer,

How many Domino machine you run behind the proxy ? Currently we have three with different fqdn so I guess that must be my iwaredir does not work well in our case. I have to configure my proxy to relay point to point address.

Regards

Sure thing, are there specific parts of it that you’re interested in?

The basics of it are using apache2 with mod proxy and mod ssl, set up your httpd-ssl.conf with a vhost for your servername to match the fqdn of the server your proxying for.
