Follow-up Comment #2, bug #60607 (project lwip): This is standard IP stack behaviour. Keep in mind the same happens for all outgoing packets. The below code is "fixed" by adding an #if or #ifdef just after netif = NULL;. At my work we use multiple interfaces for (physical) network redundancy and we need hard separation between networks, both for incoming as well as outgoing packets (in case peers are behind routers in different subnets and standard routing may choose the wrong interface). We changed both incoming as outgoing code paths to guarantee strict network separation. If there is enough interest I can ask permission to release the full patchset for merging with upstream lwIP. _______________________________________________________ Reply to this item at: <https://savannah.nongnu.org/bugs/?60607> _______________________________________________ Message sent via Savannah https://savannah.nongnu.org/
