"one ip" vlan topology

Hi All,

 

 

I'm still fairly new to BIG-IP and am trying to configure it in a 'flat' network ... meaning the BIG-IP will not have an external and internal interface, but it'll be physically positioned basically (in ip) next to the real-servers it'll load balance.

 

 

What i did is: made one VLAN (192.168.1.x/24), configured Self-ip (192.168.1.2), made a Virtual Server (192.168.1.100:80) to load-balance a pool with 192.168.1.10:80, 192.168.1.11:80 and 192.168.1.12:80

 

 

The default gateway in all of this will be the firewall in front of it, being on 192.168.1.1, which will map the official ip address towards 192.168.1.2

 

 

Config made: (as far as VS,SNAT and pools go)

 

 

pool server_pool {

 

lb method predictive

 

member 192.168.1.10:http

 

member 192.168.1.11:http

 

member 192.168.1.12:http

 

}

 

snat SNAT_client {

 

translation 192.168.1.100

 

origin 0.0.0.0 mask 0.0.0.0

 

}

 

virtual VS_client {

 

destination 192.168.1.100:http

 

snat automap

 

ip protocol tcp

 

profile http tcp

 

persist CookiePersist_client

 

pool server_pool

 

}

 

 

My question: is this a good way to set this kind of thing (one IP network) up? Can I SNAT to the same IP as the one I'm using for the VS? Do I (or better not?) set up snap automap? Or does anybody have any useful pointers for me to tackle this case please?

 

 

Thanks in advance,

 

 

Johan.
