Squid + cp
Are working the captive portal when squid proxy it's up and runing???
I would expect this to work but why don't you simply set it up and let us know? It's not much to configure. ;)
Sorry for my mistake, when squid is configured in transparent mode captive portal work very well but proxy server is running as “if();” . It’s any chance to run squid in transparent mode with captive portal ?
