436642 2006-03-09 23:03:00 I think 10.0.0.138. But if I do make the static IP 10.0.0.1 in my LAN Settings then how will that IP work? It will always show up as 10.0.0.1 and people won't be able to connect to it. DarkBlade4 (9892)
436643 2006-03-09 23:42:00 I think there is some confusion going on here, which can only be cleared up with a bit of reading.

I would go into Network Connections and manually set your IP address. Use the modem/router manual to find out its gateway IP address and put that in the Network Connections.

Then when you run ipconfig it will just tell you that information and also the subnetmask you will have set, such as 255.255.255.0

Then somewhere in your modem/router setup will be hopefully a port forwarding or 'virtual server' option for you to specify port 21 with ftp protocoll to open with the local IP address of you computer.

In my case I have 5 or 6 computers networked, with just one with an ftp server. When I want to run the server I just create a 'virtual server' in my Dynalinkmodem/router using the local IP address 192.168.1.6 for the computer concerned. Then that is the only computer that is open to the outside via port 21.

436644 2006-03-10 00:30:00 if I do make the static IP 10.0.0.1 in my LAN Settings then how will that IP work? It will always show up as 10.0.0.1 and people won't be able to connect to it.
the 10.0.0.whatever addresses are only for your local network (You & your router). Your computer isn't directly connected to the internet - it has to ask the router to do everything for it & the router sends the information back. When people see your ip address on the internet, that is actually your router, not your computer.

Napt allows data that your computer didn't ask for to be sent to it anyway if it is going to port 21 so that port 21 on your computer is directly connected to the internet (using your router's internet IP address).

if that was as clear as dishwater, think of it this way: nobody needs to know that your ip address is 10.0.0.1 - you give them your internet IP address & your router does the rest.

436645 2006-03-10 09:59:00 So what number do I put in the LAN settings(do i even need to change this?)??? And what number do I put in the NAPT settings (is it the IP i found on whatismyip.com?)? Sorry for being such a nag but I still don't completely get it. Since it comes up with 10.0.0.1 do I still need to port forward, it says so in the FTP server program. DarkBlade4 (9892)
436646 2006-03-10 10:25:00 I asked my friend to try and log on but it didn't work after I set my napt settings like this: Inside ip: 'the address i found on whatismyip.com' and the outside ip as: 0.0.0.0 and my inside and outside port as 21 DarkBlade4 (9892)
436647 2006-03-10 21:37:00 inside ip should be 10.0.0.1 & outside IP should be unspecified. Greven (91)
436648 2006-03-11 08:23:00 Do i change the LAN settings? DarkBlade4 (9892)
436649 2006-03-11 09:54:00 Ok you can use something like dyndns.org and have users connect to that which will get around the dynamic IP issue.

Then all you need to do is forward port 21 to the IP address of the PC running your FTP server.

Be carefull of passive ftp as it can cause problems with some routers.

Also check that your ftp server can be "blind" with ip addresses as it may get a bit upset with some clients using ip addresses with the port command.

If you have a good router then it may take care of the ip address issues with the port command.

if your ip address is always 10.0.0.1, then you should be fine without changing your LAN settings.

436651 2006-03-12 01:49:00 I have a horrible feeling that if you ever get this FTP server going your computer will very quickly "owned" by one of the many nasties out there .

Why don't you and your friends get Googlemail accounts, and send files as attachments? This would be much safer than FTP . It's not a very secure file transfer system . . . it didn't need to be when it was produced .

You really need to know a lot more about TCP/IP and networking before you put a server on the Internet .
