i have novell 6 sp5.
i have found enable the lan static route and the destination default route
is and next hop is 10.x.x.x

why is necessary to set the default gateway?
if the default gateway is not set, what happen?
is it correct that the default gateway is a firewall?
who must be the default gateway?

i haven't set this , i have found already this setting but i don't know
the advantage or must be set otherwise there is something that not fuction.

is there someone that can explain more details?

best regards Monica
