IP Address ftp denied router port issue?

[YesM]

Hello,

I have a server IP address and manage it with Plesk.

If I have a domain name set up with ftp access, I can access ftp no problem. However, if I have a domain set up but with out the DNS pointing to my server, I can not access FTP through the IP address.

Is there a way to gain access to the vhosts root rather than the domain root?

So, connecting to ftp://111.11.111.111 does not work (error 425) immediate fail, but ftp connection via www.domain.com does work once my DNS is pointing to the correct place.

If I am on remote desktop, I can access via ftp, so is it a local router setting I need to change? BTW, my server is in Hong Kong, I am trying to access via China (arrgh).

Thanks!@
