ClearFoundation

I'm not sure I am saying this right but I'm coming from the world of Microsoft's ISA server so please bear with me.

I am looking to move from ISA server to ClearOS. Currently, we only have one external IP address but have multiple servers being published. In other words, to the outside world auburn.oursite.com, wareagle.oursite.com and tigers.oursite.com all resolve to the same external IP address but ISA server routes one of them to three different internal address.

Is this possible with ClearOS?

Thanks!

Yes 1-to-1 NAT (usually used for small subnets) or DMZ.

I don't want to send everything to the three different machines. I just want to send web requests to three different machines. Iauburn.oursite.com would get routed to internal machine a, tigers.oursite.com would get routed to internal machine b, etc.

Make sense?

Yes make sense:1-to-1 NAT By Port

Cool but if I am reading right, you would need three separate IP external addresses for the three different addresses. As of now, all three of those addresses have the same external IP address.

Yes or If you wish to have your three sub-domain go to different web server/machines and your web server supports reverse proxy functionality (mod_rewrite for Apache) you could use the web server to proxy the requests to another web server/machine. Do not forget that proxy will be taking the brunt of all the requests.

What Philippe wrote is exactly what ISA Server does. Apache does a great job with the proxy, I've used it several times, though not with CC/ClearOS. I don't believe I've seen an easy interface to do it with, so you should probably just activate the web server (which will set up Apache and some configuration files) and then modify the configuration to fit your needs.

You will not be able to use different SSL certificates for your subdomains, though, so if you need SSL you should have a certificate with all the names of the domains you need to serve from that IP.
