[jboss-jira] [JBoss JIRA] (JGRP-1880) UDP.ip_ttl is ignored and is always 1

UDP.ip_ttl is ignored and is always 1 ------------------------------------- Key: JGRP-1880 URL: https://issues.jboss.org/browse/JGRP-1880 Project: JGroups Issue Type: Bug Security Level: Public(Everyone can see) Reporter: Bela Ban Assignee: Bela Ban Fix For: 3.6 Since we switched from using a {{MulticastSocket}} for sending of multicast packets to a {{DatagramSocket}}, the time-to-live (TTL) of a packet is always {{1}}. The reason is that method {{setTimeToLive()}} only exists in {{MulticastSocket}}, but not in {{DatagramSocket}}. We cannot revert the code and use a {{MulticastSocket}} to send multicasts, as this won't reveal the real IP address of the sender, but only the multicast address, and the real address is needed to drop packets at the _transport level_. Investigate whether we could use reflection to get the {{DatagramSocketImpl}} and call {{setTimeToLive()}}.
