I just got off the phone with Linksys support as well and they are
trying to tell me that this is how it was designed to work. I will
call again tomorrow to talk to someone in the USA hopefully will
accomadate me better. I must say that this is the 2nd RV082 (1st one
died after firmware update) and 3rd fault in firmware that I have had
to struggle with. Should have gone with the SonicWall, but way to
allow my customers go for the cheaper route! Anyway, I pointed out the
same discrepency in the manual and he claimed that it didn't
invalidate his case. He said that it is supposed to work just like DMZ
which to anyone who works on firewalls knows is BS. My emails have
also been fruitless. 2 case #s and not a single valid response. I have
gotten conflicting responses however... one said it was like that by
design and the other said that I was doing it wrong and needed to call
for support. Nothing but trouble when Support is outsourced. Dell gave
me the same problem until I got to someone in the US. Anyway, enough
rant... I will post results if/when I get them.
