Because of the way simeth is implemented you cannot ping the local host IP address from within the simulated kernel. > I can ping the simulated ethernet from any machine on the network > except the one the simulator is hosted on. That's also normal. The simulated ethernet is using a packet filter and the host interface is put in promiscuous mode. The filter routes all broadcasts + packet for the simeth address to the simeth driver, the rest goes to the local host interface. I believe such configuration forbids sending from the simeth back to the local host and that's why pinging in any direction does not work. -- -Stephane
