Forward SNMP traps using snmptrapd without changing the source IP?
However, if the SNMP traps happen over UDP (and I think they do, SNMP generally travels over UDP) you can use something like samplicator to receive and re-send the traps while spoofing an IP address. The -S flag tells it which IP address to spoof.

- How do you force local DNS server usage?

Help: UDP proxy/relay to multiple destinations
This tool should help with the UDP duplication beyond the two target challenge with iptables: https://github.com/sleinen/samplicator - still, some additional details on the app/data being transmitted would help; data actually push only? Did you verify that targets other than the original host would correctly interpret the data?

Network Hub (not switch)
You could also flip this idea on its head and point the feed at something which will replicate the packets to both the endpoints, like samplicator, which you could run on one or the other of the servers if you wanted. I use this sometimes to replicate netflow or syslog data. It does create a bit more dependency chaining, but is simple and basically 'free'.

Multiple Netflow Export Destinations from Fortigate
I can't say for sure on the Fortigate, but I use Samplicator for duplicating flows to more collectors than my equipment can export to.

Samplicator
Samplicator is a simple tool for receiving UDP datagrams on a given port and resending them to a specified set of receivers for occasions when you need to export NetFlow traffic to more than one NetFlow collector. Can also be configured to individually specify a sampling divisor N for each receiver that will only receive one in N of the received packets. crankynetadmin adds, "It's normally used for replicating netflow data, but can also replicate any UDP traffic."
- Service/app to rebroadcast/relay WOL packets?

nfsen vs fastnetmon for sFlow and DDoS monitoring
As another commented mentioned we use Samplicator. Works for lots of different UDP traffic.

Unifi Express - Ad Blocking
I just purchased the unifi express and I have been researching its capabilities and more specifically ad blocking functionality. I have found that people are complaining about the ad blocking abilities not being very granular and referring to unifios-utilities and running something like pi hole or adguard as an alternative. Can I safely assume that these options will be available to the unifi express?
