Hallo Group,
i want to implement a syn Flood Protection on our linux Router.
on our Cisco we have this Access-list and rat-limit
rate-limit input access-group 190 128000 128000 128000 conform-action transmit exceed-action drop
access-list 190 deny tcp any any established
access-list 190 permit tcp any any
access-list 190 deny ip any any
now i was trying to wrote the same config with tc
iptables -A PREROUTING -i $uplinkdev -t mangle -p tcp --syn -j MARK --set-mark 1
tc qdisc add dev $uplinkdev handle ffff: ingress
tc filter add dev $uplinkdev parent ffff: protocol ip prio 50 handle 1 fw police rate 128kbit burst 10 mtu 15k drop flowid :1
But many from our Customers can't connect to our Webservers.
what is wrong on my config?
cu thomas braun
