The redirect def1 is a server option.
But even if you have these routes in place.
They only affect traffic if you're using the "default" gateway on a firewall rule.
Policy routing forces traffic directly to an interface/gateway and bypasses the routing table.
Could you show a screenshot of the rules you think are not working with these routes in place?
Even another alternative would be, that you add on top of these rules another 4 rules (0.0.0.0/2, 188.8.131.52/2, 184.108.40.206/2, 192.0.0.0/2)
