LTM : virtual server in different subnet than a vlan --> possible

Sorry about the link, try this: http://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/ltm_configuration_guide_10_1/ltm_snat.html1200756

 

 

On the left hand side of the configuration window, under Network, there is a Routes section. I would expect you would have a route here.

 

 

I'm guessing you need to add more IP addresses to your SNAT pool, or your idle timeout is set too high, that can cause the "Inet port exhaustion" message.
