TCP,

TCP sessions would sometimes “hang” in the Close Wait state. This behaviour

UPnP

 

occurred when a UPnP notification session was closed by the control point

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

(usually Windows XP, SP2), via a “200 OK” message that contained a

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

“Connection: close” field, that also had the TCP/FIN flag set.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Because these TCP sessions were not closing, eventually all available TCP

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

resources could be used up, preventing new TCP sessions from opening.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

This issue has been resolved. Such TCP sessions now close correctly.

Switch

Previously, if all configured IP interfaces were down or had been deleted,

broadcast frames were not sent to the switch’s CPU. This meant, for example,

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

that VLANs on the switch did not receive PPPoE traffic if all IP interfaces were

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

down.

WAN load

An issue occurred when the router accessed multiple WAN load balancer

balancer

 

healthcheck hosts, and was configured as a firewall that performed enhanced

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

NAT. Instead of testing the health of each healthcheck host through every WAN

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

LB resource (and therefore over all relevant WAN interfaces), the router only

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

tested through one WAN LB resource. If that one WAN interface lost connectivity

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

to the Internet, the WAN LB incorrectly thought that all WAN LB resources had

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

become unavailable.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

This issue has been resolved. The WAN LB now correctly checks the health of all

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

healthcheck hosts through all WAN LB resource interfaces.

Firewall

When the firewall was enabled, it failed to process some RTSP packets, so clients

This issue has been resolved.
