When we implement NAT-PT under Linux 2.4.20.
Everything seems ok!
BUT! When we want to port it on uClinux 2.4.20 with MIPS compiler.
It has something wrong with following messages:
./nat-pt: initialise_packet_filter: Error setting IPv4 device packet filter: Invalid argument
...and does not work anymore
We guess, it might happen at "setsockopt(*pDesc, SOL_SOCKET, SO_ATTACH_FILTER, pFilter, sizeof(*pFilter));"
What are we missing?
Any hint/comment apperciated.
