Question about kerberos and iptables

[Tanasescu Mihai]

Hello,

I've just started to read stuff about Kerberos and I wanted to ask you
if it's possible to authenticate a network of users with kerberos to a
central linux router and upon successfull authentication to
automatically insert an iptables rule to allow that IP address passage
on the internet.

Something like: user1 authenticated => execute iptables -t nat -A
PREROUTING -i eth2 -s ip_user1 -j ACCEPT


Thanks,
Mihai
