[pve-devel] [PATCH] update update_nf_conntrack_max && nf_conntrack_tcp_timeout_established after modules load

[Alexandre Derumier]

/proc/sys/net/netfilter/nf_conntrack_tcp_timeout_established
and
/proc/sys/net/nf_conntrack_max

are empty by default, because conntrack module is not loaded, until we have apply iptables rules

So, we just need to update them after iptables commit (which load the conntrack modules)
