We've had a problem with a D-Link router/firewall. Communication within the DMZ interface was crippled by a lot of duplicate packets while communication to and from other interfaces just worked, and we just couldn't figure out why. After some experimenting earlier today we found out that the problem had to do with the switch connected to the DMZ interface. For some reason the D-Link and the Micronet switch didn't like each other. When we replaced the Micronet switch for a small D-Link switch the problem went away. For the record: the hardware that didn't play well together was a D-Link DFL-200 and a Micronet SP586A EtherFast 10/100 Mbps Dual Speed Hub. The replacement switch that solved the problem was a D-Link DES1005D.
