Hi All

I have just set up an LVS node, the config all looks sane however packets 
reaching the real servers have not been rewritten.

[root@lb0 ~]# ipvsadm -L -n
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
  -> RemoteAddress:Port           Forward Weight ActiveConn InActConn
UDP  77.75.109.11:514 rr
  -> 10.75.109.20:514             Masq    1      0          0         
  -> 10.75.109.21:514             Masq    1      0          1         



packets arriving on a real server are not re-written:

[root@graylog0 ~]# tshark port 514
Running as user "root" and group "root". This could be dangerous.
Capturing on eth0
  0.000000 77.75.107.106 -> 77.75.109.11 Syslog 106 CRON.INFO: Sep 30 22:01:01 
cron[96298]: %CRON-6: (root) CMD (newsyslog)


has anyone seen this before? any pointers at all?

Cheers

Dan
