Is the router (or switch) expecting the packet on the vlan? If so, maybe you need to send on vlan3 rather than genet0. The genet interface has some oddities about packet layouts; that could be hitting here. You could try disabling TCP TX checksum offload: ifconfig genet0 -txcsum -txcsum6; that simplifies some of the issues. Mike > Regards, > Ronald.
