3/7/2005: DPG603 Version 3.2 Release 2M

NOTE
The importance of each revision or bug fix is noted at the end of each description. The importance levels are denoted by:

Critical – This change drastically improves stability or usability of the router and it is urged that this update is applied before calling technical support for help with a problem.

Medium – This change improves the stability or usability of the router and it is recommended that you have this update installed if you are using the feature it applies to.

Low– This change is minor and is denoted next to corrections to text or minor interface improvements.

 

Revisions:

When one of the WAN ports is in the NORMAL state and the other one is in BACKUP, Bridge mode could only be set to strict binding. It is now possible to set the Bridge Mode to Loose Binding as well as Load Balancing. (LOW)

Bug Fixes:

  1. Transparent Bridge mode learns the MAC address of a machine and reacts (answers to the ARP request) incorrectly. (CRITICAL)
  2. Certain types and lengths of data would cause a system reboot when it’s coming out of a host system. (CRITICAL)
  3. In some cases the router will create an incorrect internal route. This happens when a dynamic link is disconnected and then reconnected. (MEDIUM)
  4. If a machine, which also happens to be the Gateway of the WAN1 and WAN2 connection and tries to access a Virtual Server behind the router through the WAN2 IP, the router would always send the packets back through WAN1 even if the Virtual Server is bound to both WAN ports. (MEDIUM)
  5. Previously PPPoE disconnect was not actually performed. When the now user presses the "Connect" button on "Advanced PPPoE", the page will successfully connect. (MEDIUM)
  6. When the device is used as a DNS proxy for LAN clients the selection method of DNS servers is now Round-Robin. (LOW)
  7. An empty page of DHCP clients could be displayed while an active DHCP client list could be reduced. (LOW)
  8. Multi-DMZ bug as follows is fixed. One host IP in LAN can only be mapped to one public IP address for WAN, but not multiple IP addresses. (LOW)

VPN Revisions:

  1. Added Tunnel Status page to improve usability. (MEDIUM)
  2. Added View/Delete Group button on the status page. (LOW)

VPN Bug Fixes:

  1. User initiated tunnel shutdown/restart over PPPoE connection could cause instability. (MEDIUM)
  2. When using DPD with the option Remove Tunnel, the remote side has trouble detecting a failure. (MEDIUM)
  3. Problem negotiating Phase 2 when both WAN links share the same IP segment. (MEDIUM)
  4. When two policies are pointing at the same Remote Security Gateway IP address, the router would not know which policy to use. (MEDIUM)
  5. After the first policy is added consecutive policies do not initialize properly when Manual Key is used. (MEDIUM)

Known Issues (general):

Dynamic DNS client will not be able to update its DNS records with a range of ports in the Custom Virtual Server setting. EXAMPE: LAN port: 1024~1060 WAN port 1024~1060. (LOW)

Known Issues (VPN):

When a VPN tunnel is established the remote web page of the VPN device is not able to be accessed from remote side even if the "remote admin" option is enabled. This will make the VPN box inaccessible by its local LAN temporarily. Seconds later this is restored. This bug is identified and is schedule to be fixed on next release. (LOW)

1/26/2005: DPG603 Version 3.2 Release 2L

Fixes & Additions:

  1. Fixed memory leak caused by ICMP dead peer detection.
  2. Fixed packet queue leak when one WAN port is disabled.
  3. Fixed VPN traffic pass-thru tunnel over PPPOE connection.
  4. Fixed VPN traffic problem using Distinguished Name as remote gateway.
  5. Fixed VPN policy options set/update problems (Loss of data would occur irregularly).
  6. Added exception handlers to take care of VPN reconnection.
  7. Added ICMP keepalive target host (Encrypted ICMP traffic through tunnel) feature for DPD.
  8. Added Delete Policy/Group button on the Mesh Group page.
  9. Fixed NAT Alias bug (Alias IP was not recognized by device).
  10. Fixed VPN LOG bug. With the Keep Sent flag enabled, the VPN log message would be deleted if the syslog server is enabled.
  11. Defaut health checking method for PPPoE is changed from Traffic I/O to none.
  12. Block URL is improved.
  13. DNS Loopback works without DNS server being enabled.
  14. SNMP system time reset period is extended from about 12 days to about 248 days.
