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

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.

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

behind the firewall failed to load some web pages that used RTSP (TCP port

This issue has been resolved.
