I have a USB drive plugged into the HG659 and I have enabled sharing via FTP and Samba, created user accounts for FTP and enabled anonymous FTP access. I have also added ACL to enable FTP both on the LAN and WAN but I have left the "Starting IP" and "Ending IP" fields blank as I don't the IP addresses from which I am going to be doing the FTP.
Access from LAN works fine but not over the WAN using the modem external IP address from an external site (error 503: the user is forbidden).
Has anyone done this successfully? If so, can you share how you got things to work for WAN access?
