Filark, there are a few requirements that must be observed for you to do that and it is a little more complicated if your ISP has you on DHCP which means your IP adderess changes every so often. Here we have a fixed IP address which makes life easier for any of our people or clients trying to connect to our FTP server from the outside world. It also requires careful evaluation of your firewall settings so as not to expose everything to any casual caller that might drop by.
