Hi
Here is the trace of my test:
After the output of "now do pings!", i started to ping on computer 192.168.1.1 (MAC=00:50:fc:93:e0:9c), connected to eth1 of my bridge to computer 192.168.1.33 (MAC=00:14:22:f2:5d:70), connected to eth0 of my bridge.
=> No Responses! May it be a problem of my ethernet driver (drivers/net/fec.c for Freescale ColdFire 5485) ??
