The "nat" table is not intended for filtering, hence the use of DROP is
deprecated and will permanently be disabled in the next iptables
release. Please adjust your scripts.

# /sbin/iptables -L -nvx -t nat
[...]
Chain OUTPUT (policy ACCEPT 45827 packets, 3301166 bytes)
    pkts      bytes target     prot opt in     out     source
    destination
       0        0 DROP       tcp  --  *      *       0.0.0.0/0
  0.0.0.0/0           tcp dpt:10000
#

versus

# /sbin/iptables -V
iptables v1.4.3.1
# /sbin/iptables -t nat -A OUTPUT -p tcp --dport 10000 -j DROP
iptables v1.4.3.1:
The "nat" table is not intended for filtering, the use of DROP is
therefore inhibited.


Try `iptables -h' or 'iptables --help' for more information.
# /sbin/iptables -L -nvx -t nat
[...]
Chain OUTPUT (policy ACCEPT 5115 packets, 415189 bytes)
    pkts      bytes target     prot opt in     out     source
    destination
#

Do not filter in the nat table and you will be fine.
