Hi Suraj,

 

Try below :

On the server CLI:

route add default gw INETERNAL-SELF-IP

 

To check routing:

route -n

 

Try to ping in either direction.

 

I have below setup and it just works fine:

Internal vlan on f5 mapped to interface 1.3

External vlan on F5 mapped to interface 1.1

 

Server nic in vmnet3
