As far as I understand you have HyperV VM with openVZ kernel  
and both your containers (ct 100 and ct101) executed inside this VM, it isn't?

is IP 10.200.7.26 set on your VM or containers?
If not -- external packets will not be delivered to your host.
Otherwise you can using iptables DNAT rule on hyper-V VM and to readdress all incoming packets to IP 10.200.7.26.

IMHO this should work without additional reconfigurations.
