There seems to be a problem in the communication between a mobile node = and the foreign agent. The mobile node sends UDP packets with a source = address from its own home network to the discovered address of the FA. = Unfortunately the FA never sees these packets. It seems that packets wi= th an unexpected source address will be discarded (ingress filtering?).= Is there a way to disable this behavior? What is the right way to impl= ement MobileIP on a recent Linux kernel? Thanks in advance =A0 Joerg
