>From the client PC, when I try to access to somewhere, the gateway displays 
all files on /usr/local/gateway/htdocs directories; such as :

Apache/1.3.33 Server at Gateway.mydomain.Net Port 80
--------------------

How to solve this problem ?

but then, when I try to go to https://gateway.mydomain.net/cgi-bin/login, the 
login screen displayed. When I type the username and password, the gateway 
give an error : 

--------------------
Error

Your MAC address is undefined. Problem with the gateway?
--------------------

Within /usr/local/gateway/nocat.conf, I did configure 'IgnoreMAC 1'
But, why the gateway still asking for MAC ?

>From /usr/local/gateway/nocat.log, it said :

What is wrong and how to solve them ?
