Alc-DNAT-
Override
string 247 chars {DNAT-state | DNAT-ip-addr}[,nat-policy-name]
DNAT state = none | disable
DNAT-ip-addr = implicit enable with destination IPv4
address in dotted format (a.b.c.d)
DNAT-state and DNAT-ip-addr parameters are
mutually exclusive
nat-policy-name = name of the nat-policy. This is
an optional parameter and if not specified then the
default nat-policy is assumed.
If two parameters are present simultaneously within
the Alc-DNAT-Override attribute, then they are
separated by a comma with no whitespaces used as
delimiter.
Examples:
Alc-DNAT-Override=none
This will re-enable DNAT functionality in the default
nat-policy, assuming that DNAT was previously
disabled via the Alc-DNAT-Override=disable
attribute submitted either in Access-Accept or in a
previous CoA. If the 'none' value was received at the
time when the DNAT is already enabled, a CoA ACK
will be sent back to the originator.
Alc-DNAT-Override =1.1.1.1,nat-pol-1
This will change the default DNAT IP address to
1.1.1.1 in the specified nat-policy with name nat-
policy-1 DNAT will be implicitly enabled in case that
it was disabled before this CoA was received.
Alc-DNAT-Override = none,1.1.1.1
A CoA NAK will be returned. DNAT-state and
DNAT-ip-addr parameters are mutually exclusive
within the same Alc-DNAT-Override attribute.
