Thu 22 Mar 2012 06:57:34 PM UTC, comment #8: You could add '#define LWIP_MINIMAL 1' to keep a minimal footprint and feature set and add non-required and more conforming code and features if LWIP_MINIMAL is 0. Those of us like me putting devices on corporate lans and/or the internet may appreciate as much RFC conformance and compliance as developers can add. I know I do appreciate it. |

Wed 21 Mar 2012 03:48:09 PM UTC, comment #3: this is correct for IPv6, but not for IPv4

Wed 21 Mar 2012 02:42:21 PM UTC, comment #2: Just a note that, according to RFC, an IPv4 router has the option to either fragment the packet to fit the outgoing netif's MTU, or sending back an ICMP "Packet too big" message.

Wed 21 Mar 2012 08:58:28 AM UTC, comment #1: I'd target this at 1.4.1 since it's a simple fix which still doesn't affect many systems (forwarding is not a commonly used feature in lwIP, I guess).

Wed 21 Mar 2012 08:46:49 AM UTC, original submission:
In ip_forward no ip refragmentation is done, so that if the mtu of the target Interface is smaller than the forwarding packet, the packet will be dropped.
