IIRC hosts send a RST when they close the connection.  It's to stop the
other end getting around to answering one of the previous SYNs.

Possibly, run tcpdump or equivalent on 192.168.0.17 and see what's getting
there, and whether it is replying, if at all.  Also check the routing
tables, I've a feeling it's either eating the packets due to firewalling, or
because it doesn't know where to send the replies to due to incorrect
routing.
