LVS/NAT and LVS/TUN in same virtual service

[Richard Seabrook]

Hello,

I think the answer's going to be no, however is it possible to mix LVS/NAT and 
LVS/TUN within the same virtual service? For example, to have <VIP>:80 served by 
both NAT and TUN real servers?

I'm putting together a proof of concept for global load balancing, using 
multiple, geographically dispersed directors with IP Anycast.

My ultimate aim is to have each director with a VIP that has both local (NAT) 
and remote (TUN) real servers. Real servers may be located anywhere, including 
at director sites.

As an alternative, can you "chain" LVS virtual services? What I mean by that is 
could I have one TUN-based VIP for the geographic part of the above, which then 
includes NAT-based VIPs at each site for the local balancing?

Would it then be a bad idea to use TUN when the related NAT VIP might very well 
be on the same machine?

Thanks for any help you can give and sorry for rambling ;)

Regards,
