Routing via several interfaces for hosted virtual machines

My setup consists of a hardware node, which hosts several virtual machines (OpenVZ, to be precise). The hardware node has two network interfaces (<ifA>, <ifB>) connected to different subnets (<networkA>, <networkB>). I want to route the traffic of certain VEs over <ifB> while routing the other VEs...

ipsec_tncfg

IPSEC_TNCFG(8)							Executable programs						    IPSEC_TNCFG(8)

NAME

       ipsec_tncfg - manipulate KLIPS virtual interfaces

SYNOPSIS

       ipsec tncfg
	     ipsec tncfg --create virtual
	     ipsec tncfg --delete virtual
	     ipsec tncfg --attach --virtual virtual --physical physical
	     ipsec tncfg --detach --virtual virtual
	     ipsec tncfg --clear
	     ipsec tncfg --version
	     ipsec tncfg --help

KLIPS

       Note that tncfg is only supported on the KLIPS stack which uses ipsecX interfaces bound to physical interfaces

DESCRIPTION

       The purpose of tncfg is to attach/detach IPsec virtual interfaces (e.g. ipsec0) to/from physical interfaces (e.g. eth0) through which
       packets will be forwarded once processed by KLIPS.

       When using the MAST stack, tncfg is used to create and delete virtual interfaces known as mastXXX. mast stands for Mooring and XXX.

       The form with no additional arguments lists the contents of /proc/net/ipsec_tncfg. The format of /proc/net/ipsec_tncfg is discussed in
       ipsec_tncfg(5).

       The --attach form attaches the virtual interface to the physical one.

       The --detach form detaches the virtual interface from whichever physical interface it is attached to.

       The --clear form clears all the virtual interfaces from whichever physical interfaces they were attached to.

       Virtual interfaces typically have names like ipsec0 or mast0 while physical interfaces typically have names like eth0 or ppp0.

EXAMPLES

       ipsec tncfg --create mast12
	   creates the mast12 device.

       ipsec tncfg --create ipsec4
	   creates an ipsec4 device, but does not attach it.

       ipsec tncfg --attach --virtual ipsec0 --physical eth0
	   attaches the ipsec0 virtual device to the eth0 physical device.

FILES

       /proc/net/ipsec_tncfg, /usr/local/bin/ipsec
