yesterday night I spent some time to configure my ISPConfig so that it would listen to port 80 - as described in the Howto mentioned above by Till.
Some comments on that:
1. I don't know why, but I had to adjust the VirtualHost settings:
Maybe it's because my machine runs on a Virtuozzo virtual server?
2. The performance when addressing ISPConfig via Proxy is awful. Every now and then I get proxy errors because of failed DNS requests, etc. So it looks that I might have another problem on my system that has to do with the resolver?!
3. When it comes to system configuration, I'd rather use SSL. So did you think about adjusting the howto for a SSL configuration?!
4. Once I can reach ISPConfig through my main Apache, there is no need to have the ISPConfig-Apache publically accessible. Is there a way to make this webserver a purely internal machine that is only accessible by proxying through the main webserver?
I'd love to read more about these subjects. Thanks loads in advance!
