I might be wrong, I was using Filezilla to connect, I set it up as a SSH connection and it connected. This is a stock DNS 323 with the latest Dlink firmware upgrade. I have read a little from http://wiki.dns323.info.
I have never set up a VPN connection, it would be nice to have this instead.
What I am trying to accomplish is to have to PC share the same network drive. One PC would be on my LAN the other would be outside my LAN. If you know of any good tutorials on setting up a VPN, please let me know. My router is a Linksys WRT54GS2
