The port 80 proxy is disabled by default, as many servers have an existing web server on port 80 which would conflict with the proxy.
Note that in order to enable the port 80 proxy, you MUST have an available IP address on which NO EXISTING WEB SERVER is running. You can accomplish this in one of two ways:
1) Remove any existing web server entirely. That is the simplest method, if you are not using the existing web server for any web sites.
2) Ensure that you have multiple IP addresses on your server, and reconfigure the existing web server such that it does not use the IP address on which you wish to install the port 80 proxy.
The procedure for reconfiguring your existing web server will depend on many factors and is outside the scope of our support services; contact your hosting provider or systems administrator for assistance with that.
You can change the IP address used by Centova Cast's web proxy by editing /usr/local/centovacast/etc/web.d/cc-proxy.conf and reading the documentation within that file.
Finally, to enable the port 80 proxy, run:
/usr/local/centovacast/sbin/setproxy on /etc/init.d/centovacast restart
If no errors are displayed, then the port 80 proxy is ready to use and can be enabled for each account on the Limits tab of the account settings.
