CR00021821 IPsec 3 In certain situations on an IPsec network, queued packets were not
discarded despite reaching their retry timeout period.
While a router or switch is establishing a Security Authorisation with its
peer, it keeps a queue of the packets waiting to be sent across the network.
These packets have a retry timeout period and if this period is reached, the
packets should be discarded.
This issue has been resolved. Packets that reach their retry period are now
discarded from the queue.

CR00022301 Bridging 3 Previously if ATM was used as the WAN interface in a remote bridge and
the bridge had more than 1 VLAN, then the VLAN module would drop the
bridged frames.
This issue has been resolved.

CR00023011 LT2P,
Firewall
3 Previously, the firewall on the router or switch would block some L2TP
control messages during a route change (for example, when a PPP
connection was coming up). This issue has been resolved.
