Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

Assuming that your server ip address is 192.168.1.x add the following commands

ip nat inside source static tcp 192.168.1.x  20 interface fastethernet4 20 extendable
ip nat inside source static tcp 192.168.1.x  21 interface fastethernet4 21 extendable

interface vlan1
ip nat inside

That should work. I hope your provider is assigning a specific public IP address to you.
