@Burakkucat, this stuff doesn't apply does it? Because the box should now be in modem-only mode? - Just passing through PPP frames and doing nothing itself otherwise on the Internet?
Basically I assume there's a lot of UI which is now "n/a - don't care", as long as we're sure it's not being a router? Is that correct?
Is this similar to my DLinks, in that it can also be a router? Seeing as I see things such as UPnP mentioned. If it also has a WAN-facing IP address outside of the PPP pipe, where would that address value come from? Of course, inside the PPP pipe there's no need for firewalls or such because that's the router's job further downstream. Does it have a WAN-accessible IPv4 address for admin purposes?
Need de-confusing.
* Would anyone be willing to do a basic security review / sanity check on this device in bridge mode, after config?
Have been a bit under the weather recently, as all the drugs had made me really sick. So that's me scrounging for help again.
