I see input box for port number in WAN / NAT Passthrough / FTP_ALG Port, but how can I disable FTP_ALG completely?

Create a firewall-start script with the following:

#!/bin/sh

rmmod nf_nat_ftp
rmmod nf_conntrack_ftp

#!/bin/sh

modprobe -r nf_nat_ftp
modprobe -r nf_conntrack_ftp

EDIT: Using modprobe -r is preferred over rmmod.
