Thanks.
Like the lmgtfy link ;) cheers for that. Rookie error!
My router only seems to let me specify a range and an ip for port forwarding? Is this normal? I've read that I should be able to forward a port on the router to different port # on a device.
e.g. I have an ftp server on my NAS but also on my Raspberry Pi. If I forward 21 to the IP of the NAS, does that mean I can't forward it to the pi? If I used say, 2021 for the Pi, would ftp still work or would it need to be on port 21?
One last question, I'm new to setting up ftp, I've only ever used it for work where it's already been set up and I just drag and drop in windows! But I was using it on both devices last night and I was able to copy files from each, but not write to them. I presume there are some permissions I need to change to allow this or do I just need to use ssh command line or similar? Can I limit the write access to specific IPs?
Thanks
