Java + firewalls (iptables) Posted: Feb 17, 2005 8:48 PM

Hi,
I'm planing to realise the following solution in JAVA:
Clients on a network segment use one Gateway (Router) to get access to other segments beyond the gateway.
The router redirect them first to a web server where they need to supply a username and a password. Upon successful authentication a JAVA-Programm will manipulate the iptables-Rules so that authenricated clients can pass through.

All suggestion and hints other than commercial solutions are appreciated

At http://www.pleasanton.k12.ca.us/amador/grades.html there's a whole ton of online password validication applets. Veiw source to see how it's done! PS: please don't hack any grades! The districts VERY CYA (cover your <censored>), and a break-in would send them into a deep comatose state, flooding the local hospitals with underpaid morons trying to get through life without anyone noticing they're ruining thousands of kid's lives.

I'm not sure how much Java manipulation of the Netfilter iptables firewall you need, but a commercial Java Netfilter iptables API does exist:
