Hi you,
my daughter is spending to much time in websurfing and ICQ chatting and I want to limit this. Therefore I created the following iptables firewall script and made it active via cronjob:
After that, web surfing does no longer work. Thats OK. But she is still able to chat via ICQ, if the connection was established before the script became active.Code:iptables -A FORWARD -s 192.168.1.123 -d 0/0 -j REJECT
How can I make it work, that exististing TCP connections are killed?
Cheers,
Thomas
