Hello Simon,

I am unable to ping the real server from the director (ping 174.121.60.50).
I also carried out an HTTP request and got results from trpdump and that is
the message I showed below.

ipvsadm -Lcn on the director outputs:
IPVS connection entries
pro expire state       source             virtual            destination
 
I also have no iptables running at this stage.

Kind regards,

Cyrus

By ping do you mean ICMP echo? The dump above looks more
like the result of an HTTP request?

What does the output of ipvsadm -Lcn look like on your linux-director?
And can you check that it doesn't have any iptables rules that
might be getting int he way.
