Anyway, ftp is not working because it needs both a connection initiated from the client, and one initiated back to the client from the server. It's that latter that's not working, because of rpppoe's firewalling. Netscape is probably using passive FTP. You can do this too. If you're using the plain ftp client, issue the command 'passive' from its prompt. I have used ssh successfully from within a router firewall, not rpppoe, and had no problem; and it only uses one outgoing connection, as far as I know, so I don't know what the problem is there. I guess you could try to find out whether rpppoe restricts port 22 traffic for some reason, though that would seem silly, if it allows telnet!
