Hello Laura, I've forwarded you off list the message log file. The only strange thing I see is in message.2.gz, at Dec 1 18:36:28
(all dropped packets you will see are because we use customer firewall rules to block access to a farm)
The algorithm used is Weight. The type is DNAT. IP Persistence is used in 2 farms. The 3rd farms is not using it. Thanks On 19/12/2014 11:25, Laura Garcia wrote:
Hi Tibz, could you attach the /var/log/messages log file? Which kind of algorithm are you using? What about the NAT type? And finally, are you using IP persistence?
