connect with my lacie Ip from another computer

Hello
Maybe this is a stupid question but my problem is:
I use in another location (another IP) the wget function from the nas with rapidshare (copy / paste link) and I am very happy with this function
There is some web when I create a link to copy to my nas dont allow because the link is only valid for the current IP
There is any way to create from another location a link with my IP adress?
I have a static IP "xxx.servebeer.com" and i use it to connect to my nas from other locations but there is some way to connect with this IP ??
