Subject: update update_nf_conntrack_max && nf_conntrack_tcp_timeout_established after modules... 
X-Git-Url: https://git.proxmox.com/?p=pve-firewall.git;a=commitdiff_plain;h=46a2ac1f32537b92e309965580494d05d2a54fe5

update update_nf_conntrack_max && nf_conntrack_tcp_timeout_established after modules load

/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)
