I actually did this a few days ago.
Just add both the public and the private IP address to the VE using
these commands (don't use veth interfaces):

HN# vzctl set 100 --ipadd [publicip] --save
HN# vzctl set 100 --ipadd [privateip] --save

In the VE you should now have two ethernet devices: venet0 and venet0:1
To make it actually work, you have to add routes inside the VE to the
network that isn't available using the default route:

VE# route add -net [privatenetwork] netmask 255.255.255.0 gw [privateip]

So to explain the above command, you add the route to [privatenetwork]
(i.e. 192.168.1.0) using its own IP address as the gateway. You can add
this route to one of the startup scripts of your VE, so it gets added
when the VE boots.

Remember, this only works when your Hardware Node knows both networks
(in its routing table).
