iptables connlimit match
Author: Gerd Knorr <kraxel@bytesex.org>
Status: ItWorksForMe[tm]
This adds an iptables match which allows you to restrict the
number of parallel TCP connections to a server per client IP address
(or address block).
Examples:
# allow 2 telnet connections per client host
iptables -p tcp --syn --dport 23 -m connlimit --connlimit-above 2 -j REJECT
# you can also match the other way around:
iptables -p tcp --syn --dport 23 -m connlimit ! --connlimit-above 2 -j ACCEPT
# limit the nr of parallel http requests to 16 per class C sized
# network (24 bit netmask)
iptables -p tcp --syn --dport 80 -m connlimit --connlimit-above 16 \
--connlimit-mask 24 -j REJECT |
