Configure server for deluge seedbox (help with ram)

1. I have a server that I'm using for hosting files on my website 2. I want to keep the server still active but also have (deluge) installed as well on the server, 3. I want to keep my current settings on my server (hard disk mounts, etc.) but install deluge 4. After deluge is installed I would need help with a proxy ip on the server so my servers ip isn't used, but the proxy ip 5. would like to keep server memory at a minimum (I have 8gb ddr3) but would like to ensure deluge doesn't take up more than 1gb
