Patch Release Note

Features in 86222-21

Patch 86222-21 includes all issues resolved and enhancements released in previous patches for Software Release 2.2.2, and the following enhancements:

PCR: 02167

Module: FIREWALL

Network affecting: No

Locally generated ICMP messages, that were passed out through a firewall interface because they were associated with another packet flow, had their source address changed to that of the associated packet flow and were also forwarded with incorrect IP checksums. This only occurred when there was no NAT associated with the packet flow. This issue has been resolved.

PCR: 02236

Module: FIREWALL

Network affecting: No

Sometimes the retransmission of an FTP packet was not permitted through the Firewall. This issue has been resolved.

PCR: 02245

Module: VRRP

Network affecting: No

VRRP returned an incorrect MAC address for an ARP request. This issue has been resolved.

PCR: 02327

Module: IPG/FIREWALL

Network affecting: No

In some situations, multihomed interfaces caused the Firewall to apply NAT and rules incorrectly when packets were received from a subnet that was not attached to the receiving interface. This issue has been resolved.

PCR: 02329 Module: DHCP

Network affecting: No

An ARP entry for a host has been removed whenever a DHCP DISCOVER or DHCP REQUEST message is received from the host. This allows for clients changing ports on a switch.

PCR: 02332

Module: IPSEC

Network affecting: No

The sequence number extracted from the AH and ESP header was in the wrong endian mode, which caused an FTP error with IPSEC anti-replay. This issue has been resolved.

PCR: 02343

Module: PPP

Network affecting: No

When acting as a PPPoE Access Concentrator (AC), if a PPPoE client sent discovery packets without the "host-unique" tag, the discovery packets sent by the AC were corrupted. This issue has been resolved.

PCR: 02368

Module: IPG/IGMP

Network affecting: No

IGMP failed to create an automatic IGMP membership with no joining port when it received multicast data that no ports were interested in, when IP TimeToLive was set to 1 second. Also, IGMP erroneously sent a query on an IGMP enabled IP interface even when IGMP was disabled. These issues have been resolved.
