Firewall 2 When the WAN load balancer was used with IP NAT (instead of firewall NAT), and

an FTP session was established to a server on the public network, the router did

not correctly establish a return session. This meant data was unable to flow

correctly back from the server, and the router rebooted.

This issue has been resolved.

Note that the WAN load balancer is not designed for use with IP NAT, because IP

NATs are not associated with interfaces. Configurations that use an IP NAT cannot

vary the global IP address (the gblip parameter) based on the outgoing interface,

so the WAN load balancer sends all traffic out with the same source address.

Therefore, the return traffic probably comes back via the WAN load balancer

resource that is associated with the global IP. The impact is that the WAN load

balancer balances the outgoing traffic but not the return traffic.

We recommend using firewall NAT instead of IP NAT with the WAN load balancer.

VRRP,

IP Gateway

2 Under certain network conditions in which VRRP entities become temporarily

unsynchronised, the router or switch could receive a gratuitous ARP from a self-

elected VRRP master when the router or switch was still the master. This caused

the existing master to create an ARP entry that incorrectly redirected packets

towards the other VRRP entity even after the other entity had become a slave

again.

This issue has been resolved. The router or switch no longer accepts gratuitous

ARPs from other VRRP entities while it is still the Master.

Switch 2 After the AR770S rebooted, the Port Link/Activity and Duplex/Collision LEDs

sometimes did not blink in response to activity and collisions, respectively.

This issue has been resolved. The router detects the problem and recovers from

it, if possible. If it cannot recover from the problem, it generates a log message

of severity 6, module SWK, type REST, and subtype FAIL. The log message says

“An LED error has been detected, please power-cycle the device. If this message

appears again, contact your technical support representative for help.”
