Running iperf on ac68u

[banz]

This is a dumb question. I'm doing some benchmarking on my ac68p with iperf installed.

On my router, I'm running it as a server
iperf -s

On a offsite client, I'm trying to connect to the router via
iperf -c <external ip of router>

By default iperf listen on tcp 5001. On port forwarding page. I setup port forward tcp 5001 to my router ip which is 192.168.1.1 and on internal 5001 port. My offsite client is not able to reach my router. I then temporary disable firewall completely. Now I'm able to get to it. So I think I'm somehow messing up the port forwarding?

It's not sufficient to just forward the port. In fact you shouldn't need to forward the port at all because iperf listens on the WAN interface.

You need to allow the incoming connection through the firewall of the device running the iperf server, which in your case is the router. So...

iptables -I INPUT -p tcp --dport 5001 -j ACCEPT

Yeah that worked. I just thought port forwarding will punch a hole through the firewall. Thanks
