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.

MLD Snooping

Routers snooping group contained more than one port and another snooping

group contained no ports. In this situation, when a port timed out of the All

Routers group, multicast traffic from the empty snooping group was flooded to

all ports on the switch. Flooding continued until the last port timed out of the All

Routers group.

This issue has been resolved.

deleted first.
