x86_64 Multicast on 18.104.22.168
We had a multicast solution until we upgraded to 22.214.171.124 and 64 bit dual core CPU. We also added a second NIC. The kernel was built with IP_MULTICAST,IP_ADVANCED ROUTER,IPIP,IPGRE,IP_MROUTE == *. The terminal receives all unicast messages, does join the multicast group, even occassionally send the multicast report to the group address. I can see messages come into the eth0 but the kernel never forwards them to the waiting socket/process. I've added smcroute but nothing changed. Does anyone have this type of issue? IPtables firewall was not built into this release.
Thanks in advance.
