No. Linux (and hence ip_vs) don't handle fragmentation for 
tunnelling properly. After you change the max packet size 
for packets from the director to the Tun realserver, then 
the client will be sent a "needs fragmenting" icmp packet. 
If this packet makes it back to the client, then your LVS 
should start working again.
