Firewall 2 When only NAT was enabled on the firewall, during some TCP connections in
which either end of the connection sends FIN (finished) messages immediately
after sending some data and the other end ACKs (acknowledges) the data and
the FIN message consecutively, the firewall sometimes incorrectly interpreted the
first ACK message (intended for the data) as belonging to the FIN message and
prematurely shut the connection down. This could prevent the firewall from
opening up new connections using the same port numbers.

BGP,
IP Gateway
2 When BGP learned new best routes for a particular destination, it did not always
clear any active IP flows that used the previous best route. Therefore, the router
or switch continued to forward traffic sub-optimally.
This issue has been resolved. Now, when BGP inserts new routes into the IP route
table, it deletes all active route flows, so any active flows change to using the new
route. The time taken to delete a full table of IP flows has also been greatly
reduced.

Switch 2 Sometimes IP routed traffic would be sent out the correct port, but with the
destination MAC of another device on the network. This issue was most likely to
occur in configurations that use multi-homed interfaces on multiple VLANs for
end devices.
This issue has been resolved.

Switch 2 When the command enable ip macdisparity was used, and a static ARP entry
was configured with an L2 multicast MAC address, the switch should have
broadcast traffic to that multicast MAC address out all ports in the VLAN. This
was not happening.
This issue has been resolved.

VRRP 2 After manually disabling the master VRRP router, sometimes a backup router that
should assume master status would not do so, and VRRP would cease to function
properly.
This issue has been resolved.
