     here i am using sify broadband, with different  LAN ip and WAN ip . my  LAN ip is static and WAN ip is assigned by sify when i login to internet service .
     i configured my PC to provide FTP connection  , but my friends r not able to connect my PC
through ftp by using my WAN IP as well  as LAN IP.
     But i am able to connect to my friends PC through FTP using internet  . although he is located
 so far away from me ( in different city) his isp is different from me .  

     so how can i locate my PC over internet. my means my friends can connect to my PC using
 FTP or remote login .

     help me to find out my ftp address of my PC  on internet .

    you need to make sure FTP is set up on your computer in IIS.  then also make sure your router is forwarding port 21 to your computer.  your friend would use your external (WAN) ip to access your computer.

    Hi, you can go to to see your internet IP.  I presume you have a firewall/router for your WAN connection... what kind is it?

    Configuration will vary by model, but there should be a configuration option to take inbound FTP requests to your WAN IP and send them to your LAN IP.

    it is possible that your internet company gave you an "internal ip address" instead of external.  Many internet companies are doing this anymore to not have to have so many ip addresses in their bank.  They send you through a router of theirs and give an internal address.   Do you know the ip address that your router picks up?

    Compare your router's external IP to what is reported at  If they are different like JimsZ thinks they might be, then you are probably out of luck as far as inbound connections are concerned.
