yes, I have read viewtopic.php?f=6&t=3507&p=18424#p22384
Nevertheless I can't figure out where the Problem is.
My Server is running openSuSE 12.1
I tried turning the firewall off, custom firewall rules, adding 188.8.131.52/24 to the routing table.
I don't get any clue about dropped packets from the firewall-logs.
Multicast is enabled on the Network-interface, kernel has multicasting-support.
I have absolutely no more ideas, how to solve this problem.
is there any way, to reduce the interval of the ALIVE-transmission?
