Things are alright when I send to unicast IP addresses, but when I send to multicast addresses (224.0.0.0 - 239.255.255.255) the IP stack (maybe?) replaces the TTL field with a 1. This would restrict propagation of the packets under construction. Can anyone give me a clue why this is happening and how to overcome it? Thanks.
