But to address the actual question... ;)
DISCLAIMER: I work for NSC. I own stock. I do not work on this
BG does have flaws that have made it hard to sell as a router, most
notably, it does not talk OSPF (yet), and it doesn't have very many media
types. You currently get the one ethernet built in, and can get up to three
WAN cards of various standard types (V.35 etc), but you don't get ISDN (yet),
you can't get Token Ring or a 2nd ethernet (yet), you won't get 100Mbps
anything. I don't know the status of demand dialed things, but if it's
there, it's pretty recent (i.e. was not in there when the pricing was
laid out). So it's priced 'typically' for a low-end router. As a VPN box,
however, it seems to be a real bargain.
Keep in mind that pricing on a box like this is primarily market
driven. Everyone else prices their little bitty router at $US995 plus extras,
getting you up to (typically) $US2000-ish, so we must do the same.
Customers who would prefer to pay more are, of course, welcome. Just
send any additional funds you'd like to pay direct to me, I'll ensure that
they're properly handled ;)
I really hope someone NOT from NSC jumps in here somewhere, though.
