No. C-Servers has designed a custom provisioning module for the VirtFusion panel that allows the customer to benefit from a different NAT system. This is the standard NAT IPv4 arrangement of port range allocation, as most customers know it, directly routed to/from IPv4, without any IPv6 needed for it to work. All NAT port assignment and configuration is directly handled from VirtFusion's own control panel, or what we call now - the VirtPanel.
