every piece of documentation i have read about L2TP suggests that packets
involved in the l2tp connection cannot be modified in any way, so you cannot
use LVS-NAT - maybe LVS-DR would work, but since pptp and l2tp involve
several connections (udp, tcp, gre), it's would be tough to balance the
several streams streams of data of the same connection to the same server.
Just a suggestion, but what do you gain by using 2 lvs directors to
loadbalance 2 concentrators, that you wouldn't get by 2 concentrators
running heartbeat for failover in an active-active config (unless the
concentrators are not linux, but some os that can't run heartbeat ) ?
