For testing purposes I changed the ssh rule to: -A TCP -p tcp -m tcp --dport 22 -j ACCEPT -A TCP -p tcp -m tcp -s 0.0.0.0/0 -d 192.168.2.5 --dport 22 -j DROP
And still no go. As mentioned before, everything works fine until I try to close up the rest of the ports not opened up in the chains "UDP" and "TCP" stated above: #echo -e " - Dropping input TCP and UDP traffic to closed ports" -A INPUT -i $INTIF1 -p tcp -j REJECT --reject-with tcp-rst -A INPUT -i $INTIF1 -p udp -j REJECT --reject-with icmp-port-unreachable #echo -e " - Dropping output TCP and UDP traffic to closed ports" -A OUTPUT -o $INTIF1 -p tcp -j REJECT --reject-with tcp-rst -A OUTPUT -o $INTIF1 -p udp -j REJECT --reject-with icmp-port-unreachable #echo -e " - Dropping input traffic to remaining protocols sent to closed ports" -A INPUT -i $INTIF1 -j REJECT --reject-with icmp-proto-unreachable #echo -e " - Dropping output traffic to remaining protocols sent to closed ports" -A OUTPUT -o $INTIF1 -j REJECT --reject-with icmp-proto-unreachable That is when I cannot SSH over to the server.
