Max network interfaces supported by Networker vProxy

Hi,

I've see, deploying the last ova for Networker vProxy, that via ova GUI is possibile to define 2 network interfaces only.

Does it mean that max 2 network interfaces are supported on a vProxy ?  May I add a third interface later on using commands on the vproxy?

There is a document where is stated max num of network interfaces supported?

Thanks in advance for any suggestion/reply
