Hi all, We're trying to run some tests against an ISC DHCP failover DHCP pair using perfdhcp. Unicast works well, but we can't simulate broadcast traffic (sending to 255.255.255.255 or the broadcast address of the subnet, with -B set).
We're running the tool in a Docker container in host mode, in privileged mode (so it can send broadcasts). If I set the destination to 255.255.255.255, we see packets exiting the host (using tcpdump) going to "255.255.255.255" - but these don't appear to hit the DHCP servers and nothing is coming back to the host. It may be an infrastructure/firewall thing, but do we know whether this is possible to generate broadcast packets using the tool / can anyone please shed some light on how to get it to work if so?
