Hello, former03 | Baltasar Cevc a écrit :
Does pc2 try to send out the packets (see tcpdump output)? - If yes, it's probably your ISP blocking 'spoofed' packets (packets which come from adresses that are not supposed to be on that subnet).
Right. But even though the ISP does not block "spoofed" packets, I replied in comp.protocols.tcp-ip that an SNAT rule cannot change the source address of a reply packet.
