This is lwIP's routing scheme: any packet that does not fit a netif 
subnet is sent to the gateway of the default netif (set with 
netif_set_default()). And if the default netif does not have a gateway, 
or you haven't set a default netif, these packets will be lost.

In never versions, see define LWIP_VERSION in init.h. If you cannot find 
that, your version is very old (and you should probably upgrade, anyway).
