We just reported a bug to Dell regarding their last 2 generations of 
remote access controllers where the firewall rules only apply to TCP and 
not to ICMP or UDP. Their first response was to replace the motherboard. 
Second response was that this is just how they work. Not looking good. 
We run our IPMI interfaces behind stateless ACLs, accessible from VPN or 
trusted ranges.
