Re: [lwip-users] problem with multiple UDP sockets

[Mario Ribeiro]

Hey Fabian,

Thanks for the enlightenment! :)

I was looking at my wireless connection parameters instead of the ethernet. Now I use IP 169.254.232.150 with netmask 255.255.0.0  and it's working!

Best regards,

Mário Ribeiro

Hey Mario,

 

this looks like your communication partner doesn’t have the right IP set as target:

 

ip_input: iphdr->dest 0xFFFFFEA9 netif->ip_addr 0x4301A8C0 (0xFFFEA9, 0x1A8C0, 0xFF000000)
ip_input: packet not for us.

the destination IP is: 0xFFFFFEA9, which is 169.254.255.255 (that is the AutoIP range that e.g. windows assigns if it doesn’t get an IP from dhcp).

And that is certainly “not a packet for us” since your netif has 192.168.1.67 with a netmask of 255.255.255.0

 

Does that help?

Otherwise, create a wireshark capture of the traffic.

 

Kind regards,

Fabian
