Iptables is actually a collection of 3 or more filters or tables - INPUT, FORWARD and OUTPUT. For this, I'll assume it's an input to port 10000 you are looking for.

When you wish to specify a port number or range of ports, you must also specify a protocol - TCP, UDP, ICMP, ALL.

so the command line might look something like this:

iptables --append INPUT --protocol ALL --source-port 10000 --jump ACCEPT

Which reads "append the INPUT filter to ACCEPT ALL protocols with packets with which are destined for port 10000"

Hope this helps some :)

Oops! I'm sorry I must have been falf asleep! It seems that you must specify a protocol - TCP or UDP. so that the rule might look like this:

# iptables --append INPUT --protocol TCP --source-port 10000 --jump ACCEPT

And if you need UDP it would be:

# iptables --append INPUT --protocol UDP --source-port 10000 --jump ACCEPT

But if you need both, then you would use both commands:

# iptables --append INPUT --protocol TCP --source-port 10000 --jump ACCEPT
# iptables --append INPUT --protocol UDP --source-port 10000 --jump ACCEPT
