The point of having different routing tables is exactly that: having different routing tables. Each table is technically independent. However, if a particular table does not come op with a route for a packet to take, the next rule is investigated, and if it matches the packet, a route is searched in the table looked up from that rule. For most rulesets one would end up using the routes in table main... In your case I don't see how that can occur, as you have a default route in table isp1. However, what *does* occur is somewhat of a mistery to me. Could you show us your full routing tables (ip route show table all) as well as the routing cache (ip route show table cache) with and without the default route via w.x.y.z dev eth1? (You may want to run a ip route flush table cache first... this will make the route cache somewhat more palpable.)
