I'm not the one running NATD, it's my ISP. I have one static IP, and that's it. Well... Both passive ftp and dcc use random high ports on both ends. Passive ftp works great from the client side through a firewall but is a rather large pain on the server end behind a nat/firewall. Basically you have to redirect _all_ tcp ports over 1023 to your machine. Active ftp is easier because it uses port 20 (ftp-data). -Mark To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
