first, what you want to achieve is very doable (not that i know the
netgrear stuffs but for sure it must be). If the client do not nego
split tunneling (destination policy/route is 0.0.0.0/0), then probably
that your problem is simple routing. A network schematic would for sure
help in giving advices, but simply follow the packet with a sniffer.

On thing, does the vpn client receive private inner tunnel ip addresses
trough mode-config or l2tp ? This is important for routing in this case
and may well be your problem if they dont.
