I am having trouble getting netperf to work through a Linux iptables firewall.
I have created an allow rule for TCP/12865 and for TCP with
state=Established,Related on the machine that will be running netserver.
However, after successfully connecting from a client machine, the server
drops TCP packets that are destined for ports in the 1024-1030 range. Here
is an excerpt from /var/log/messages:
Mar 12 13:39:59 basis16 authpriv.info netserver[440]: connect from
10.1.253.254

What iptables configuration is required to get netperf to be fully operational?
