two servers on the same port

ruyterb · 06-29-2013, 09:32 AM

Hi,

I want to make two servers available on the internet through the same external IP address. These servers use the same port (443) but have a different URL (server1.mydomain.com and server2.mydomain.com). I searched for reverse proxy, layer 4 routing, etc. but found no suitable solution.

My preference would be something like zeroshell or pfsense (complete system, fast & low demands, robust) but as far as I can see these cannot provide such routing.

Any suggestions?

Thanks in advance!

At the transport layer, two (or more) servers cannot share the same port.

The solution, as you've correctly deduced, is to do this at the application layer by setting up a reverse proxy. Unless you're using a wildcard certificate covering both server names, you will need to install both SSL certificates on the proxy and make sure SSL 2.0 is disabled.

I did a Google search for "pfsense reverse proxy", and got quite a few hits (including this), including instructions on how to install SSL certificates.
