Patch 54266-01

PCR: 40613

Module: SYN

Level: 3

When the Test facility was used to test an AR023 synchronous PIC interface, it sent some debugging messages, "SYNCheckInterface", to the console port. This issue has been resolved: the Test facility no longer sends these messages.

PCR: 40618

Module: Firewall

Level: 3

When NAT was enabled and the router was configured to pass FTP requests to a server inside the network, the Firewall translated the ftp-data source port (tcp/20) of an FTP server located on a private interface to another port. Such packets no longer conformed strictly to RFC 959, and some other firewalls on the Internet may then have denied them. This issue has been resolved: the Firewall now sends all ftp-data packets from port 20 on the firewall, whether or not NAT is enabled.

PCR: 40619

Module: IPG

Level: 2

The output of the show config dynamic command incorrectly displayed the following parameters for the set ipv6 prefix command, even when they were not specified with the command:

•The valid parameter displayed an incorrect value; the router did not use this incorrect value.

•The preferred parameter displayed an incorrect value; the router did not use this incorrect value.

•The onlink parameter displayed the default value yes.

•The autonomous parameter displayed the default value on.

This issue has been resolved: the unused parameters are no longer displayed.

PCR: 40625 Module: SWK

Level: 2

The GUI on the AR441S did not display a port map on the System Status page. This issue has been resolved. GUI resource file d441Se14.rsc or later is also required to display the port map on the AR441S.

PCR: 40629

Module: Firewall

Level: 2

A fatal exception in the firewall occurred occasionally when a large number of proxied connections were rapidly established, for example, during a SYN attack. This issue has been resolved.

PCR: 40633 Module: ENCO

Level: 2

The encryption engine on the AR441S was not initialised. 3DES outer, 3DES inner and AES encryption algorithms were not available. This issue has been resolved.

PCR: 40638

Module: Firewall

Level: 2

When a global interface was dynamically assigned an IP address via DHCP or PPP, NAT configurations with dynamic private interfaces (interface=dyn-<dyn-int-name>) were not updated. This resulted in the failure of sessions received on dynamic private interfaces because the global IP address was invalid. This issue has been resolved.
