Hi, I have dynamic IP address from DSL ISP and I installed the DDNS services, I can't remote connect my PC use Windows Remote desktop, then I installed FTP server, tested ok to access FTP server from LAN computers, but can't reach from the outside internet. I have configure Firewall for FTP and remote desktop pass through. I can't ping my IP address and the DDNS domain name from the outside computer, (Always time out) but computers inside the LAN ok to ping the DDNS domain name and resolve my dynamic IP address and acces to FTP server. How can I configure my FTP server and remote desktop can be reach from the outside world? please advise, Thanks a lot!

If you are using a router/firewall like a linksys, you probably need to do more work if the only thing you did was open those ports up and didn't forward them. I'm also assuming this is so and that you signed up for a ddns service like no-ip.com & registered a domain name with a someone like Network Solutions. If you haven't already, you have to forward port 21 (ftp) & 3389 (rdp) from the external ip address to the ip address of the internal computer hosting those services. All routers that I know of have this feature and have simple instructions in the manual for setting it up. Sometimes Internet service provider will block certain ports for security reasons. You may want to call and check. It doesn't hurt. Most don't and if they do, it's usually port 25 (smtp-email) to cut down on computers being used by spammers. Hope that helps.

From what you describe, it sounds like the DDNS is not resolving your domain name to your dynamic public ip. If you just set it up, it may take a little time for it to become operational.
It seems like you have done the other things right.
