Identity NAT configurable proxy ARP and route
lookup
8.4(2)/8.5(1) In earlier releases for identity NAT, proxy ARP was
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.
