My trouble is related to manage udp traffic generated from a custom application that uses packet with size limit at 7900 byte. This type of traffic is not correctly received from packet filter driver, that is not able to understand source and destination port. So, it’s not possible to correctly manage this traffic.

I’ve seen that the value of 1514 bytes is indicated in the .H library. Do you think that is possible to change this value ? Which value do you suggest me? I’ve seen that packets are correctly managed also in the case that the size of packets is lightly bigger than 1514 bytes (my tests tell me that all is correctly done with a size up to 1573 bytes. Over this value the packet is not correctly received.

Thank you in advance for your support.
