Captive Portal SSL Problem

User_333 — Mon, 27 Jun 2011 15:44:10 GMT

I tried to configure my PaloAlto with a captive portal, but something seems to be wrong, as i don't get any login form.

As I use the captive portal in redirect-mode, the firewall forwards my browser request to something like https://publicWLAN:6082. This seems to work right. I also got a "allow" Log entry on my traffic log.

I tried to analyze the traffic from my test-computer (Wireshark on my test-computer) to this https://publicWLAN:6082/... . I can see a TCP-Session setup, ONE SSL Hello from my Client to the Firewall and Session close packets (initiated from firewall). So it seems to be something wrong with the SSL handshake.

So, how can I debug this SSL handshake on the Paloalto.

Hirslanden,

Where did you get your certs from?

You might try using firefox with firebug to help with the troubleshooting,

What do the PAN logs say?

If your stuck you should contact Paloalto support and allow us to help you through this.

Hi Phil

Same Cert works fine with SSL VPN. I generated it on the PaloAlto. I tested the Captive Portal with a external generated Cert too.

In which logfile should I find some capitve debug messages.I took a look at a lot of logfiles but couldn't find any useful information.

It was the Certificate...bit I don't understand why the same Cert works fine with SSL-VPN.

Additionally, my AV-Scanner did some strange things which got me some wrong debug results.
