Ok well lets try this in a slightly different approach:
(FYI: I don't work for buffalo but if you'd prefer to PM me some of the data that's fine. Otherwise if you'd like to modify your datasets, we can work w/ that, just keep the #'s consistent for discussion ;) ).
What is the LAN (local) IP of your Linkstation?
For your 2Wire 2701, are you running DHCP on it?
According to your 2Wire 2701, what is your WAN (true) IP address?
How did you setup port forwarding, and did you go to "Firewall settings" to 'allow access' to the Linkstation as a host for that?
Shouldn't use DMZPlus mode or whatever 2Wire calls it, seems to be problematic (well there's also security risks etc).
Finally this might answer PCPiranha's question...
For internet acccess, do you need to launch anything on your computer, or are your username + password for dsl inside your 2Wire device for automatic login?
Thanks,
