Hi All, Currently setting up some new 3030S devices which I have recently upgraded to 4.0.1. We are setting up source NAT and the idea was to use the ve IP addresses for the associated vlan as the source NAT address in the pool. I swear we had it setup like this in version 2.7.2P6. but since the upgrade it says we can not use the ve interface IP address as the source nat address in a pool. Is there anyway of using the interface address as the source NAT now? Just trying to keep the number of IP addresses used down. Thanks Ryan ---

Hi Ryan, This should be possible with “Smart NAT” which will use the interface IP or VRRP Floating IP. Per admin guide: Smart NAT provides source NAT for virtual ports. The IP addresses that Smart NAT uses to create the mappings depend on whether VRRP-A high availability is enabled and floating-IP addresses are configured: • With VRRP-A high availability – If VRRP-A high availability is configured, Smart NAT uses configured floating IP addresses as NAT addresses. • Without VRRP-A high availability – If VRRP-A high availability is not configured, then Smart NAT uses IP address(es) on the ACOS interface connected to the real server. The configuration is applied to the VPORT with “source nat auto” command. Mike ---
