[lvs-users] Ldirectord in Fedora Core 6 problem with squid

[Graeme Fowler]

Hi

Change your iptables rule; at the moment you can get packets
"reflecting" from one host to the other - you seem to be running two
directors which also host the squids, aren't you?

If the directors have MAC addresses MAC1 and MAC2, then you need to do
the following:

director1:
/sbin/iptables -t mangle -A PREROUTING -p tcp --dport 80 \
  -m mac ! --mac-source $MAC2 -j MARK --set-mark 1

director2:
/sbin/iptables -t mangle -A PREROUTING -p tcp --dport 80 \
  -m mac ! --mac-source $MAC1 -j MARK --set-mark 1

That prevents packets looping, causing the problem you see.
