When I first setup my Linux server for IP Masquerading and firewalling, I had problem with FTP. A kind soul send me the following fragment that I use for as part of my firewall rules. I'm not sure if this is what you're actually looking for: # Allow clients to use FTP through gateway # ipfwadm -I -a accept -P tcp -S 0/0 21 ipfwadm -I -a accept -P tcp -S 0/0 20 /sbin/modprobe ip_masq_ftp Martin wrote:
