Network Object NAT

8.3(1)

Configures NAT for a network object IP address(es).

 

 

 

We introduced or modified the following screens:

 

 

 

Configuration > Firewall > NAT Rules

 

 

 

Configuration > Firewall > Objects > Network

 

 

 

Objects/Groups

 

 

 

Identity NAT configurable proxy ARP and route

8.4(2)/8.5(1)

In earlier releases for identity NAT, proxy ARP was

lookup

 

 

disabled, and a route lookup was always used to determine

 

 

 

the egress interface. You could not configure these settings.

 

 

 

In 8.4(2) and later, the default behavior for identity NAT

 

 

 

was changed to match the behavior of other static NAT

 

 

 

configurations: proxy ARP is enabled, and the NAT

 

 

 

configuration determines the egress interface (if specified)

 

 

 

by default. You can leave these settings as is, or you can

 

 

 

enable or disable them discretely. Note that you can now

 

 

 

also disable proxy ARP for regular static NAT.

 

 

 

When upgrading to 8.4(2) from 8.3(1), 8.3(2), and 8.4(1),

 

 

 

all identity NAT configurations will now include the

 

 

 

no-proxy-arp and route-lookup keywords, to maintain

 

 

 

existing functionality.

 

 

 

We modified the following screen: Configuration > Firewall

 

 

 

> NAT Rules > Add/Edit Network Object > Advanced NAT

 

 

 

Settings.
