# Do not edit, changes to this file will be lost on upgrades
# /etc/sysctl.conf can be used to customize sysctl settings

net.netfilter.nf_conntrack_acct=1
net.netfilter.nf_conntrack_checksum=0
net.netfilter.nf_conntrack_tcp_timeout_established=7440
net.netfilter.nf_conntrack_udp_timeout=60

Put these lines in /etc/sysctl.conf

net.nf_conntrack_max=16384
net.netfilter.nf_conntrack_max=16384

then run sysctl -p to reload settings from file.
