I am trying to get a captive portal working with a NAT'd proxy server.
The CP is on opt1 and the proxy is on the LAN. I have an outgoing rule
to forward all web traffic from port 80 to 8080 on the proxy server.
The only problem is that I have to add a rule in the CP to allow bypass
to the proxy for this to work - which means that I never get a login.
Is this setup possible? What is the general idea behind it?
