Does net.ipv4.conf.all.accept_redirects = 0 in /etc/sysctl.conf make kernel to ignore ICMP redirects for all interfaces or1) do I have to set it for particular interface like net.ipv4.conf.eth0.accept_redirects = 0
or 2) do I have to set a rule in iptables like iptables -A INPUT -i eth0 -p icmp --icmp-type 5 -j DROP Thanks in advance. Best regards Georgi
