internal and external on the same network

Hello

 

how can i do then the sample configuration. Needs to have external and internal with the same network

 

 

 

 

external

 

| 192.168.100.30 virtual server

 

192.168.100.33 self ip

 

--------1.3------------------

 

| BIG IP | ( 1.3 and 1.2 is interface)

 

|-------1.2------------------

 

| internal vlan self ip 192.168.100.44

 

|--------------------|

 

| switch |

 

---------------------

 

| |

 

node 1 node 2

 

192.168.100.60 192.168.100.62

 

 

It seem that i do not need to create ip address for internal and vlan address. Other ideas.

 

Thanks
