Hello,

 

I have had the same case and yes my Internal VLAN was on Application subnet, the same one is used for servers so you don't need any additional routing between those.

 

External VLAN (i.e public VLAN) was on different subnet and proper routing must be done in order for clients (or other network elements) to see LB (Virtual IP is used for external clients).

 

And as "What Lies Beneath" said usage of SNATs should come in handy also.

 

Regards,
