<pre>Patch didnt help Pablo. Listing this small set each second from patched box:
testbox ~ # nft list set filter private
table ip filter {
set private {
type ipv4_addr
flags interval
elements = { 10.0.0.0/8, 100.64.0.0/10, 172.16.0.0/12,
192.168.0.0/16}
}
}
testbox ~ # watch -n 1 nft list set filter private > /dev/null
and testing latencies of packets going through this box (actual traffic is
1.2Gbps, real address is replaced by a.b.c.d):
karel2 karel # ping a.b.c.d -i 0.1
