How to set sharedNAT on lowend VPS?

On lowendstock.com has been taken for the exercise of VDS to the terms of the 20 port NAT IPv4 and 1 IPv6 address.
And then there was a problem in the intake ports on VDS,
The contract was given a range of IPv4 NAT ports 100-120.
SSH perepechino and works perfectly. Apache IPv6 is given, as in other and all the rest.
But here's the thing. I can not understand how to organize the reception ports on IPv4 within the provided range.
For example, the organization receiving 80 and 443 port.
Control panel SolusVM. The service provider NatVPS (Hostrails).
Can anyone encountered this problem?
