Running FTP server behind NAT

To run a FTP server behind NAT:

1. Go to menu Settings ->Advanced ->Port Mapping
2. Add new Port mapping:

Protocol: TCP

Listen IP: unspecified or IP address associated with the domain. Such IP address must be associated with the Internet Interface

Listen Port: 21

Destination IP: enter the IP address of the internal FTP server (e.g.192.168.1.10)

Destination Port: 21

Note: Clients in passive mode will try to open a new connection on port 20. WinRoute will dynamically allocate this port so there is no need to create an additional port mapping.
