How to configure an FTP site in IIS with external IP address

Hello,

I’m trying to host 2 FTP sites with IIS.

I can get to the default site by typing ftp://mail.companySite.com

I need to create another site for our customers to download and upload files, so I was going to simply create another FTP site at the same address on a different port, but an IT guy said I would be better off with another public IP address….so now I have the new public IP address, and I believe it is pointed at the machine that is running IIS….my question is, should this external IP address be pointed at the IP address of the phyical server that is running IIS or should I create an FTP site in IIS, give it an IP address and then have the external IP address point at the FTP site IP address??
