Since you only have one VIP on the realserver, then there is only one instance of the server running on it. The director will send ipip packets to both x.x.x.200 and x.x.x.124, but both streams will arrive at the lo==VIP. I can't see how to do what you want with LVS-Tun. You can do it with LVS-NAT. > > lo Link encap:Local Loopback > inet addr:127.0.0.1 Mask:255.0.0.0 > inet6 addr: ::1/128 Scope:Host > UP LOOPBACK RUNNING MTU:16436 Metric:1 > RX packets:14352327 errors:0 dropped:0 overruns:0 frame:0 > TX packets:14352327 errors:0 dropped:0 overruns:0 carrier:0 > collisions:0 txqueuelen:0 > RX bytes:2971562342 (2.7 GiB) TX bytes:2971562342 (2.7 GiB) > > tunl0 Link encap:IPIP Tunnel HWaddr > inet addr:192.168.100.203 Mask:255.255.255.255 > UP RUNNING NOARP MTU:1480 Metric:1 > RX packets:458 errors:0 dropped:0 overruns:0 frame:0 > TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 > collisions:0 txqueuelen:0 > RX bytes:29063 (28.3 KiB) TX bytes:0 (0.0 b) > squid's squid.conf > http_port 192.168.100.124:80 transparent > squid2's squid.conf > http_port 192.168.100.200:80 transparent the service has to listen on the VIP, not the RIPs.
