Well, as a start to "masqd", I've written a filter that doesn nothing.  It
receives a packet, outputs bits of info, then inserts it back into the IP
stream (after fixing the IP checksum if it's an "in" packet).

Works fine for tcp connections (telnet at least) & udp (NFS at least), but
only half-works for ICMP.  It gets the incoming ICMP (ping), fixes the sum
and does the sendto(), but never sees the reply.  The reply is received by
the sender though.....

Is anyone currently working on this divert code ?  Or should I fix this ?

TIA.
