I got my SE on the internet via FTP with MacTCP 2.0.6 and Fetch 2.1.2. Works like a charm.

All I did was install the Asante driver for my nic.

Configure MacTCP to use Ethernet (provided by the Asante driver)

Set my IP to Manual, punch in my gateway and DNS addresses (setting Domain name to "."), and manually enter an IP address

Install and run Fetch.

I connected to my webiste no problem and was able to get/put files.
