[tor-relays] port setup

I have a Westell A90-750018-07 router and I need to set up port forwarding for port 9001 and 9030. My router won't let me do it however, saying: *Invalid End Port value of NULL Please enter a valid number* when I attempt to do so. I entered 9001 in the *Global PortStart *box and**the other empty boxes on the setup page are *Global PortEnd *and *Base HostPort.* What values do I put in the Global PortEnd and Base HostPort boxes????* * TIA. Art* *
