MockLab7 ver 5.0 task 2.9
Lab Do's and Dont's says "Do not use any static routes, default routes, default networks, or policy routing unless otherwise specified". Task 2.9 does not specify that static route is allowed, unlike task 2.10 which clearly allows 1 static route.
SG uses static route "ip route 188.8.131.52 255.255.0.0 null 0". I also used static route, otherwise there is no way to solve this task
