The conflicting route is

route outside 1

You cannot add 2 default routes. You can enter a more specific route eg.

route online

Note - the above is just an example. But you cannot have 2 entries for the same route ie.

Dear Jon,

You mean on ASA not allow use many default route, right?Is it can use only one default route?this is the rule right?

Best Regards,

Apologies i should have been more specific. You can multiple default-routes with the same cost but they must go out the same interface - see link for more details:

You can also have 2 default-routes with unequal cost ie.

route outside 1

You could then add your other default route with an admin distance higher than 1

route online 2

Note the number at the end of the route statements ie. 1 in your first statement and 2 in the second statement. The ASA will always use the route with an AD of 1.
