OpenVZ - Reverse path filtering (rp_filter ) - sysctl.conf


I have changed rp_filter (Reverse path filtering ) to loose mode (rp_filter = 2) on the hardware node. I belive that this has fixed the intermittent network connection loss in the VM's.

####syct entries###
net.netfilter.nf_conntrack_max = 196608
net.nf_conntrack_max = 196608
net.ipv4.conf.default.rp_filter = 2
net.ipv4.conf.all.rp_filter = 2
