is there any way to duplicate incoming udp traffic on port 162 and forward to multi ports like 162 itself and 1600? I was checking iptables but it seems only able to redirect to a single port/host.

Thx Luke

There is an experimental TEE target to iptables' mangle table which is part of the Xtables-addons (ex patch-o-matic) which is able to copy a packet without changes to another gateway. There you could NAT to another port, if still needed.

flow-fanout will do what you want:

  • it likely won't - flow-fanout is to replicate NetFlow exports, not generic UDP data. – the-wabbit Feb 23 '13 at 7:59

I'm pretty sure you can also configure net-snmp as a trap receiver to relay traps to other devices if you have multiple monitoring stations you are trying to send data to.

I just found samplicator which also seems to do this.

  • +1 for samplicator - it appears to be exactly what we need for duplicating statsd traffic to ensure HA on our Graphite solution. – Saustrup Jul 4 '17 at 12:54
