CR00020319 SNMP 3 ASN.01 BER padding is now enabled by default. This means that SNMP
adds 0x00 padding when the most significant 9 bits of an object’s value are
all 1. Padding enables legacy SNMP NMS systems to correctly decode this
value, and provide correct readings.
Previously the default was for the encoding to follow the ASN.01 BER rule,
which cuts off the most significant byte of 0xff.
This setting has an impact on all integer type MIB objects, including 32 bit
and 64 bit counter objects.
To remove the padding, and return to using the ASN.01 BER encoding rule,
use the command:
set snmp asnberpadding={off|no|false}

CR00020833 IP 3 When using IP NAT, TCP connections would have the sequence and/or
acknowledgement numbers incorrectly altered by the router, which
prevented the TCP connections from being properly set up.
This issue has been fixed. Please note that NAT configured using the
Firewall was unaffected by this issue.

CR00021128 Firewall,
VRRP
3 Previously, when VRRP was configured on a router or switch that also had
a Firewall NAT rule involving the same VRRP IP address, when the router or
switch was in the Backup VRRP state it would reply to any incoming ARPs
for the VRRP IP address with its own MAC address.
This issue has been resolved. When VRRP is in the backup state, it will never
reply to ARP requests for the VRRP IP address under any circumstances.
