8:35 a.m.
it's a normal desktop machines iptables firewall:
If i want to block udp on dport 80 on the output chain, then is this enough? i want to only allow tcp on it! iptables -P OUTPUT DROP iptables -A OUTPUT -o $PUBIF --dport 80 -j ACCEPT
or i need this rule? iptables -P OUTPUT DROP iptables -A OUTPUT -o $PUBIF -p tcp --dport 80 -j ACCEPT
the second one is the good one?
