by default the nf_conntrack_tcp_timeout_established is quite huge (5days),

cisco firewall have 2hour by default

it could be great to have a tuning option,

I found a doc here:

with recommandation of minimum : 7875

tcp_keepalive_time + tcp_keepalive_probes * tcp_keepalive_intvl = 7200 + 9 * 75 by default)
