Yeah, they started rolling out a firmware update on the 5168's (and possibly the 3801's?) with some new features.
I noticed in the old firmware, under NAT, there was X/1024 NAT sessions (where X=available sessions) but this is now gone on the new firmware. Would like to get an explanation as to why they changed it. My guess is that too many people were using too many at a time. Apparently 700 or less available meant something on your local network meant something like torrents were hogging bandwidth.
