CR00021338 PPP 2 Previously, PPP could unneccessarily reduce the memory available on the
device for other services when configured as a PPPoE access concentrator.
This occurred when a client repeatedly attempted to connect and failed (for
example because of authentication failure). When the session was
terminated, buffers were left allocated to the session, causing the amount
of memory available to steadily reduce.
This issue has been resolved.

CR00021633 Firewall 2 When the firewall received an 500-level error from FTP, it did not always
clean up the firewall sessions associated with the FTP connection. This issue
has been resolved.

CR00021772 IGMP snooping 2 Previously IGMP Snooping caused a memory leak when a host joined or left
a multicast group. This was because memory allocated when the host
joined the group was not returned to the memory pool when the host left
the group.
This issue has been resolved.

CR00022084 Bridging 2 Previously, if a bridge filter was configured with port=none the running
configuration on the router or switch would actually be set to port=all.
This issue has been resolved.

CR00022092 UPnP 2 Over a long period of time UPnP would exhaust the number of available
TCP connections on the device and not release them. This has been
resolved.

CR00022692 Port
Authentication
2 In certain network configurations, when an AR770S required authorisation
from a Port Authentication device, the AR770S would fail to respond to the
request packet sent from the Authenticator. This occurred only if the
Authenticator was in multiple-supplicant mode (enabled using
mode=multi in the enable portauth port command).
This issue has been resolved.
