Now, I hope the whole message will be delivered without blanks and tabs.
I`m sorry for the previous one.

****************************************************************************
*********
I have this working:

VIP:80
 ServerA:80 (other subnet, so with TUN)
 ServerB:80 TUN
VIP:8080
 ServerC:8090 (multiple instances, so with NAT)
 ServerC:8190 NAT

¿But is there a way to have this working?

VIP:80
 ServerA:80 TUN
 ServerC:8090 NAT
 ServerC:8190 NAT

If not, is trying something like this (balancing between the balancers)
worthwhile?

-------------------------------------------------------------Director
VIP:2222
----------------------------------------------------(Balances load with NAT
between
-----------------------------------------------------Director_TUN and
Director_NAT)

------------------------------Director_TUN
VIP_Tun:80-----------------Director_NAT VIP_Nat

------------------------------ServerA:80
TUN-------------------------------ServerC:8090 NAT
----------------------------------------------------------------------------
--------ServerC:8190 NAT

¿Should I choose between jumps and multiple instances or do you think there
could be a way to have the balancer working with both features?

Thanks,

Mikel Ruiz

you can only have one forwarding method for each virtual
service, so that the load balancing information
for all realservers is in one table. So you can't
have the director with VIP:80 forwarding this
service to realservers by TUN and by NAT at the same
time.

the rest of this didn't survive the e-mail.
Try with small number of blanks and no tabs.
