Julien,
Make sure that all interfaces are covered if you have more than one:
net.ipv4.conf.all.arp_ignore=1
net.ipv4.conf.eth0.arp_ignore=1
net.ipv4.conf.eth1.arp_ignore=1
net.ipv4.conf.all.arp_announce=2
net.ipv4.conf.eth0.arp_announce=2
net.ipv4.conf.eth1.arp_announce=2
You don't need the hidden stuff (don't think its in Ubuntu anyway.)
also
ipvsadm -Lnc
will show a lot of SYN_RECV if you are getting ARP issues.

> ipvsadm -a -t $VIP:80 -r $RIP1:80 -g
> ipvsadm -a -t $VIP:80 -r $RIP2:80 -g
>
> On webservers, I added the following to /etc/sysctl.conf (as suggested on

> net.ipv4.conf.all.hidden = 1
> net.ipv4.conf.lo.hidden = 1
>

> Unless I did something stupid (if so, please tell me), it should work. I

> echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore
> echo 2 > /proc/sys/net/ipv4/conf/all/arp_announce
>
> I'm quite sure my problem is not on the loadbalancer but on webservers.
