2750 with Bt infinity works well
however unable to open port 5000 to 5200 for ftp to readynas
I use a port forwarding tester
the error i get is
miniupnpd[30993]: addnatrule() : iptc_is_chain() error : No chain/target/match by that name



Any help greatly appreciated

FTP is Port 21. I would supect the port range you're using is for the ReadyNas control software. If you only want to access the ReadyNas by FTP from the WAN Port 21 is all you need.

Thanks for your help
