Hi All,

I found the solution n this post viewtopic.php?t=148734

Virtualization Station does not care of networking, so i create the iptables rules to get it work on my qnap using shell:

iptables -t nat -A PREROUTING -p tcp --dport 1194 -j DNAT --to-destination my_nas_ip:1194
iptables -t nat -A POSTROUTING -p tcp -d my_vm_ip --dport 1194 -j SNAT --to-source my_nas_ip
