when I create a loadbalancer with the following rules:

IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
  -> RemoteAddress:Port           Forward Weight ActiveConn InActConn
TCP  [2001:db8::1]:smtp wlc
  -> [2001:db8::4d82]:smtp Route   1      0          0

and telnet to that address:25 that I see that the SYN packet receives the 
director and then the director starts to send out ICMPv6 neigh solicit for its 
virtual address:

11:37:16.920154 IP6 2001:db8:ff00:33f::2.49931 > 2001:db8::1.25: Flags [S], 
seq 1035995206, win 4880, options [mss 1220,sackOK,TS val 2256545946 ecr 
0,nop,wscale 7], length 0
11:37:16.920252 IP6 fe80::21d:9ff:fe6d:3501 > ff02::1:ff00:1: ICMP6, neighbor 
solicitation, who has 2001:db8::1, length 32

Any ideas what might be wrong?

Kernel: 3.10.1
