Alright, I solved the problem by myself. The key point is that the backend servers should also allow ip spoof(only required for lb’s DSR mode), then the packet sent to vip will be delivered to correspond virtual nic. By the way, I created vip as lo0:1, it’s a virtual interface and won’t response to arp protocol by default.

I’ve tried create a alias for lo0 ipadm create-addr -t -T static -d -a 10.20.1.244/24 lo0/server0 but it doesn’t work. also I can’t create alias for net0 because I did’t enable ip spoof in backend server(and it should be disabled). I used tcpdump and I could see the packet from client server to vip, so the rule in lb should be right, but the backend server didn't response. What can I do? Thanks. -------------------------------------------------------------------------------------------------------- Briphant, Ruochen Xu [email protected]<mailto:[email protected]> smartos-discuss | Archives<https://www.listbox.com/member/archive/184463/=now> [https://www.listbox.com/images/feed-icon-10x10.jpg1d3216c.jpg?uri=aHR0cHM6Ly93d3cubGlzdGJveC5jb20vaW1hZ2VzL2ZlZWQtaWNvbi0xMHgxMC5qcGc] <https://www.listbox.com/member/archive/rss/184463/27846711-c61ff54c> | Modify<https://www.listbox.com/member/?&;> Your Subscription [https://www.listbox.com/images/listbox-logo-small.png1d3216c.png?uri=aHR0cHM6Ly93d3cubGlzdGJveC5jb20vaW1hZ2VzL2xpc3Rib3gtbG9nby1zbWFsbC5wbmc] <http://www.listbox.com/> ------------------------------------------- smartos-discuss Archives: https://www.listbox.com/member/archive/184463/=now RSS Feed: https://www.listbox.com/member/archive/rss/184463/25769125-55cfbc00 Modify Your Subscription: https://www.listbox.com/member/?member_id=25769125&id_secret=25769125-7688e9fb Powered by Listbox: http://www.listbox.com
