FTP totally fails to connect to the server if the client is NAT'd and ToE
functions are enabled on the interface doing NAT.
+--------+ +-------+ +--------+
| client |--->| nbrtr |--->| server |
+--------+ +------NAT +--------+
With ToE enabled, the interface near the server sees the SYN-ACK from the
server but immediately returns a RST. Simply disabling ToE with -tcp4sum
and no other changes the client connects and works with the server.
I'm still working on more information for the initial report. Changing ToE
did not affect the sporadic nature of the problem.
