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.

New Additions:

A new flash section- TXT_SECTION- is created to store the configuration that will be reloaded while full firmware upgrading. (MEDIUM)

Bug Fixes:

PPPoE connection authentication and re-authentication issues. (CRITICAL)

PPTP passthru time-outs. (MEDIUM)

Fixed a bug with the PPPoE multi-sessions which are only available when the first one is connected. (LOW)

User defined DNS server IP addresses are now available. (LOW)

DNS loop back when using your own DNS server. (LOW)

Fixed the bug on Protocol & Port Binding (LOW)
• Overlapped rules checking now improved
• Failure updating rules fixed

Remove the function which checks the DMZ WAN IP Checking for DHCP and PPPoE connection types. (LOW)

The port numbers 61440-65535 are reserved applications services running on the DPG Series device (example: DDNS), preventing conflicts with Virtual Servers or DMZ servers. (MEDIUM)

Tracert problem: response from gateway of the WAN port skipped. (LOW)

Fixed IP conflict when static interface set to use the same IP with DHCP interfaces. (LOW)

Fixed the bug that the firmware of device with NULL MAC address can not be upgraded. (MEDIUM)

Default PPTP MTU is changed from 1456 to 1460, and the user defined PPTP MTU can be configured via UI. (LOW)

3/7/2005: DPG502 Version 2.1 Release 2M

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)

Known Issues :

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)
