Re: [lwip-users] Netifs routing

[Norberto R. de Goes Jr.]

Sorry, my explanation was not good. 

Really I have a VM running an OS (Linux) and lwIP running inside that. 

Please, more details in picture attached.

I have been investigating  and I think that the problem is associated to PPP netif netmask (ever 255.255.255.255). Please, see the "get_mask" function  and "netif_add" call both codes in the "lwip/src/netif/ppp/ppp.c" file.

Thus, the "ip4_route" function does not match the appropriate netif, in this case the netif-1, and returns the default-netif (netif-0, associated to eth0). Then the outgoing packets are forwarding to eth and not to serial. When the client-echo is run in VM#0 the all works fine because the match happens.

Is it correct?

Thanks.

Do you actually have a VM running lwIP ???
[..] please enlighten me on how you have lwIP running by itself on a VM.

That would be fun. You "just" need to write a driver for one of the NICs supported by VMWare and somehow get a time base :-)
