Binding to a specific IP address?

[Zethrus]

Is your feature request related to a problem? Please describe.
Not exactly a problem, though I'd like to be able to bind algo to specific IP address on my machine as I have multiple.

Describe the solution you'd like
I would like to be able to bind algo to a dedicated IP that I have reserved specifically for the VPN. I do not want Algo to use the main IP address on the main network interface. Instead, I would like algo to use my secondary IP that is bound to the eth0:0 interface which I've reserved for algo, this IP is also the DDoS protected IP on my server hence why I'd like the protected IP used with Algo.

Describe alternatives you've considered
Not really any alternative to this, though I have done research via Google and found nothing in focus :(
