How to configure One ARM setup with multiple VLAN

Hi  ,

Thanks for your advise. I did setup the external and internal vlan as your told and also created self-ip and floating ip for each vlan. I also setup SNAT and it worked perfectly for me but it creates another issue. It could not preserve the Client's source IP address (We need to preserve it). If I take off the SNAT then it can't reach the Virtual server IP at all. I think an asymmetric routing occurred here but I could not find a solution to resolve it> Can you suggest me something?   

My Client IP = 10.10.100.100

My External VLAN10= selfip 1010.10.10, floating self-ip 10.10.10.12

My Virtual server = 10.10.10.50

My Internal VLAN20= selfip 1010.20.10, floating self-ip 10.10.20.12

My Nodes are on VLAN20= 10.10.20.21 & 10.10.20.22 (but their default GW IP 10.10.20.1 is at the L3 Switch, since these nodes and not directly connected to the F5). Both f5 and Nodes are VM hosts and are connected to a L3 switch.
