The use of authentic UNIX or Windows DHCP server software is recommended where the Virtual DHCP Server functions are insufficient.

I see, here are alternatives for SecureNAT (vDHCP/vNAT):
- on Windows Server edition these components already exist (RRAS + DHCP)
- on Linux simply use iptables + dnsmasq

problem solved by just editing subnet mask to 255.255.254.0
