[ULTRAMONKEY-USERS] Questions about HA + LB schemas

[Luis Daniel Lucio Quiroz]

Hi All

I'm a little new about UM3 and I'd like to implement it with a customer.  
However we are making checklist of resources we must use. 
Using high capacity HA and LB 
(http://www.ultramonkey.org/3/topologies/hc-ha-lb-overview.html) questions 
are this:

1. Because this will be at network frontier, we will use public ip's.  
Realservers are FW that use nat of to newtworks with 28 bits mask (32 public 
ip in total).  Does LinuxDirector needs also 32 public IP's in addition? Is 
there any paper that talks about this?

2. If we use this http://www.ultramonkey.org/3/topologies/ha-lb-overview.html 
for same fw,  NAT is done by who? FW or LDirector?

Regards
