any command in IOS can forward a range of ports for PASV ftp?
I have a PASV ftp server behind the NAT router. it is too painful to forward each port line by line. For forwarding 20 ports, I need to enter 20 lines. I can't image if I need forward the ports more than that.
what comand can perform that if I want to for the port 5000-6000 to private address 192.168.1.0
I hope my understanding of the CBAC is correct. it is a context based firewall, it temporary open the port based on the behavior of the application.
For the PASV, it opens the incoming port for the duration of the PASV ftp session.
In my saturation, I only have 1 public address with NAT to share the internet connection. I also have 1 PASV FTP server in the local network, it listens a range of FTP port (let say 5000-6000) for the ftp service on the local address 192.168.1.x. The NAT router forward the same range of TCP port (5000-6000) from the public address to the private address 192.168.1.x
it is nearly not possible to for so many port in command line with 1 port 1 line format. That's why I am looking for a solution for port forwarding in range.
