maybe you have to change the ip of your second internet eth1 not the eth0 for internet you maybe might using the known ip block like 192.168.1.1
because if your eth1 is 192.168.1.1 it can easily bypass your billing system... if i will configured my PC ip into same block as your eth1 ip and specify the gateway to 192.168.1.1 and the DNS server into your ISP DNS.....

Just maybe.... who knows..... your client accidentally guest the right ip of your eth1

my eth1 is DHCP so there is no ip....

in addition to my posted opinion:

as you said you are using squid. Try to remove your SQUID as transparent proxy in your server, because i think user can easily bypass Chillispot login page. if they specify server's IP address (for example 192.168.182.1) in to there BROWSER proxy setting  to HTTP proxy input and the port (usually 3128), user do not need to login to access/browse the internet.

i have tried to put ip proxy on my browser, but i can't bypass login page. i have add another rule to firewall.iptables to prevent that way.......


thanks for ur opini...

is there another way ??

I see your firewall script is the default included with ChilliSpot, except for the PREROUTING lines.  These make sense since you're running your web server on port 8080.  As far as I can tell, this configuration should be preventing all but authenticated users from gaining access.  That is unless there's an issue with your FreeRADIUS configuration.  I know this sounds obvious, but have you tried authenticating from a test client with a bad username and/or password, to check this part of the setup?

One possibility is that your uamsecret password is insecure.  Is it shorter than 16 characters or does it include dictionary words?  This part of a ChilliSpot setup is open to a dictionary attack with an insecure uamsecret password, due to the nature of the CHAP protocol.  (See the ChilliSpot FAQ entry: "http://www.chillispot.info/FAQ.html#mozTocId967226".)  Also, if this password is as short as 6 characters, even if random, it can easily be brute-forced.  It's possible this unauthenticated user has used a dictionary or brute-force attack to determine this password and gain access.  This is just a guess.  I'd recommend using a password greater than 16 characters and preferably random, if you're not already.

Another possibility that came to mind does involve the firewall.  Is your firewall script set up to run on server startup, or do you have to run it manually?  If the latter, it's possible your firewall has opened up due to a server reboot.  Many Linux distros have a default iptables policy that allows all traffic through on the INPUT, OUTPUT & FORWARD chains, and this would be in effect in that case.
