[Keepalived-announce] keepalived 1.2.13: Round robin UDP problem

[Sven L. <sve...@gm...>]

Hi,

I've build a setup with keepalived 1.2.13 where I want to round robin UDP
traffic. But all UDP traffic (syslog) of different sources is always send
to the same real_server.

/var/log/messages doesn't show any errors and I can see the health check
working via tcpdump.

I check where the syslog traffic is sent by doing a simple tcpdump.

I went through all the info I could find, but don't see anything wrong. I
also haven't found how to debug so that I can see why it decides to send
all different sources to the same real_server.

Thanks,
Sven.
