isuue for 2 servers in different subnet

Whether this is a good design depends on what you are trying to achieve. Can you provide some more information on your goals please?

OK, so you just want to 'load balance' between these servers (even though there is only one in each subnet)? Let's walk through a simple way to do this;

 

 

1) Create the two VLANs on the F5 with the same tags as you have used on your switch, lets say VLAN2 and VLAN3.

 

2) You could tag but to keep it simple, assign VLAN2 to 1.2 untagged, VLAN3 to 1.3 untagged

 

3) Ensure the correct VLANs are assigned to the switch ports, access mode

 

4) Create a Self IP for each VLAN on the F5

 

5) Configure the default gateway on each server to be the relevant Self IP of the F5 for that particular VLAN

 

6) Create a pool for each server, two pools each with one server in it

 

7) Create/modify each VS to use the pool for the server in the other VLAN

 

8) No need for the SNAT really
