I GOT IT!!!!
Maybe its stupid and everybody already knows that, but I just figured out
whats going on and I got it running, so here goes the solution, maybe this
can help someone.
I have 2 nic cards on my director with 2 different ips, from 2 different
networks.
I found that I cannot use both ips at same time for lvs, coz I need 1 ip to
be doing nothing and being the default route. this ip I cannot set on my
real server.
I took 2 servers in the same situation, 2 lines each, I put 1 line of each
server on tunl0:0 and tunl0:1 on my real server and its now working just
fine.
Thanks for all the efforts and all your attention.
That list rocks!
