13. Support Vantage CNM -- revision 2.2.00.61.03

Known Issues:

[UPnP]
1. Sometimes on screen the "Local Area Connection" icon for UPnP disappears. The
icon shows again when restarting PC.
2. When you use MSN messenger, sometimes you fail to open special applications,
such as whiteboard, file transfer and video etc. You have to wait more than 3
minutes and retry these applications.
[Bandwidth Management]
1. Bandwidth management H.323 service does not support Netmeeting H.323
application.
2. Using BWM in PPPoE/PPTP mode, there are two filters for FTP and H323 ALG
(1) If we execute FTP first then H323 cannot pass through ZyWALL.
(2) If we execute H323 before FTP, all functions work properly.
3. In some cases, BWM (Fairness-Based mode) cannot manage bandwidth accurately.
Ex. In WAN interface, there are two subclasses for FTP service, their speed are
100Kbps and 500Kbps, the traffic match the filter which speed is 500Kbps may
only use half of it's bandwidth.
[Content Filter]
1. Can't block ActiveX in some case. (Sometime the ActiveX block fails. This is
because the ActiveX is cached in C:\WINNT\Downloaded Program Files\ If you
want to test the ActiveX block functionality. Please clear the cache in windows.)
[Bridge Mode]
1. When device boots in Bridge Mode, some CI command error messages will be
displayed on console. This is because some predefined CI commands in
autoexec.net is forbidden to execute in Bridge Mode.
2. Don't use CI command "bridge rstp bridge enable" to enable RSTP, it will change
the initial Path Cost value to an incorrect value.
[ALG]
1. Symptom: P2002 can not connect with each other in Peer-to-Peer mode.
Condition:
Topology: P2002--(LAN)ZyWALL_A(WAN, IP=172.21.2.151)--(WAN,
IP=172.21.1.134)ZyWALL_B(LAN)--P2002
(1) In ZyWALL_A and ZyWALL_B, add a "WAN to LAN" firewall rule to pass
traffic with port "5060".
(2) In ZyWALL_A and ZyWALL_B, add a port forwarding rule "5060" to P2002.
(3) In ZyWALL_A and ZyWALL_B, enable SIP ALG.
(4) Setup both P2002 to Peer-to-Peer mode.
(5) Making the SIP connection by P2002 will be failed.
(6) Turn off firewall in ZyWALL_A and ZyWALL_B, sometimes the connnection
can be built up if we dial from P2002 which is behind ZyWALL_A.
[MISC]
1. At SMT24.1, the collisions for WAN and LAN port are not really counted.
2. Under PPTP encapsulation mode, we can not access some website like
http://www.kimo.com.tw/
3. In eWC->Statistics, Tx data for Dial Backup is not correct.
