Unless I try to reach the client web server from the A/Vserver, then it fails and arp says:
Address HWtype HWaddress Flags Mask Iface corp.domain.com (incomplete) eth0 dell11.domain.com ether 00:06:29:AF:A3:67 C eth1 192.168.1.254 ether 00:20:78:0F:AC:31 C eth0
One can also see the arp requests go out on eth 0 rather than eth1:
arp who-has 192.168.0.10 tell 192.168.0.254
Put
net.ipv4.conf.all.arp_filter = 1
into your /etc/sysctl.conf
and run (for the time being)
sysctl -w net.ipv4.conf.all.arp_filter=1
Linux implements the weak host model, so packages are accepted on any interface, *if* the traffic is directed at the host.
When arp is used, this model doesn't always work. That's why you should use the sysctl setting above.
