UDP MTU Fragmentation on a STM32

I'm using the LWIP library and STM32F407. I’m trying to send a 1860 bytes  through Ethernet using UDP protocol, exceeding the Ethernet MTU (1500 bytes) so my data is fragmented. I´ve used some programs to test If I could read UDP stream, but nothing works. No problem to read packets under 1500byte (with no fragmentation) with my host application or other.. However, I can see the traffic generated by this packet using Wireshark:

There is any way to read this fragmented Data properly, configuring some parameter of the LWIP library?

thanks
