I can not ping any server ip across IVS(one arm no dmz). I set up one IVS with sign-in by virtual port ip 10.146.0.199, gateway vlan 10.163.0.1. Internal port ip 10.146.0.253, gateway 10.146.0.250(gateway to intranet). Server 10.146.0.1. I can ping all my network with internal port 10.146.0.253, but I can not ping from vlan port 10.163.0.1. I do it by step of admin guide book. anything else that i missconfig or i miss any step.please show me.
