I can see http But not https !

I have Nocat gateway and Authserver in the same PC. Suse Linux 10.3 etc..
Internet ethernet card: 192.168.0.1
Local network card: 10.0.0.1
>From the client I can see the login page when I type: http://10.0.0.1/cgi-bin/login.
I cannot see it when I type: https://10.0.0.1/cgi-bin/login 
When I type any web address (example: www.google.com) I am redirected through https://10.0.0.1/cgi-bin/login?redirect=http%3a%2f%2fwww%2egoogle%2ecom%2f&timeout=600&gateway=10%2e0%2e0%2e1%3a5280&mac=00%3a0C%3a76%3a27%3a62%3a76&token=%241%2411359800%24j0cLmA5DTpLg7WwEnBMBn1 
and of cource the page is not loaded, I get error : connection is not possible, etc.. 

What's wrong?

I searched the mailing list and found nothing ! only similar problems! When they solve it they don't say how!

Thank you for helping me!
