Mon 17 Nov 2014 03:40:29 PM UTC, comment #1: There are a few scenarios, yes. For example, I have some setups with Ethernet and serial PPP modem, both are connected to the internet. I modified ip_route() so that packets are returned on the same netif as they were received. Otherwise, they are always routed back on default_netif and that doesn't always work.

There are obviously configurations where source-based routing is required. The core code should not prevent this (while preventing an impact of this feature on single-netif configurations). |
