Release Notes

June 27, 2002 (1.6.8)

Fixed bug which could cause IPNetRouter to crash when manually disconnecting a PPP connection.

June 21, 2002 (1.6.7)

DynDNS client support now automatically updates the DynDNS host information every 25 days, even if a user's public IP address has not changed. This is important for users who are using the DynDNS.org service to keep track of their current public IP address which rarely, if ever, changes.

March 27, 2002 (1.6.6)

Added option to ignore "BootP" requests in DHCP Window. Enabling this option will disable DHCP lease assignments to PCs and other machines which request lease assignment by BootP instead of DHCP.

Added support for the "CUSTOM" feature of DynDNS.org. To enable custom domains, the domain name needs to be appended with ":CUSTOM". For example:

mydomain.com:CUSTOM

will enable a custom domain name at DynDNS for this domain (hence you do not need to use one of their registered domain name suffixes).

Users can append this command to the previous wildcard enabler, as described in the 1.6.5 release notes. A domain using both commands would look similar to this:

mydomain.com:YES:CUSTOM

February 18, 2002 (1.6.5)

Fixed a radio button bug in the Exposed Host feature of the Gateway window.

Added support for the "WILDCARD" feature of DynDNS.org. To enable wildcards, the domain name needs to be appended with ":YES". For example:

sustworks.dyndns.org:YES

will enable wildcards at DynDNS for this domain.

Wildcards would permit remote users to find our machine using:

"www.sustworks.dyndns.org"
"ftp.sustworks.dyndns.org"

etc.

January 31, 2002 (1.6.4)

Added a "Show DNS" button in the Interfaces window which, when clicked, displays the ISP's current default name server address. This IP address should be used as the Name Server (DNS) field in all client machines which are manually configured (especially users of the single ethernet setup). This is also of particular interest to cable modem users who have been or shortly will be going through various conversion processes by their ISPs (i.e. moving from static IP address assignments to DHCP address assignments).

Users should also ensure that the "DHCP Aware" feature is applied to their masqueraded interface when their ISP moves their service to a DHCP assigned IP address.

December 18, 2001 (1.6.3)

Implemented DynDNS client. This lets IPNetRouter automatically update a user's dynamically assigned public IP address with DynDNS.org.

Removed date field from registration dialog box (no longer needed).

Included OTModl$Proxy v2.1.8

November 6, 2001 (1.6.2)

Increased filter table to 2000 entries.

The new payload inspection filter action is now properly displayed within the Filter Window (payload filters must be configured with IPNetSentry). Payload filters are especially useful for detecting and stopping Nimda and Code Red type intrusions.

Added button to turn off/on IPNetSentry from the Filter Window.

Added DHCP server feature which handles application specific DHCP option commands (see DHCP Help window for more information). Most applicable to other developers who need their applications to handle unique commands during the DHCP negotiation process.

Include OTModl$Proxy v2.1.7

Aug 15, 2001 (1.6.1)

Fix bug in Local NAT with new OTModl$Proxy 2.1.5. This will mainly affect users who need to use the "Enable Local NAT" feature in the Gateway Window of IPNetRouter.

Released as 1.4.2

Sep 29, 1999 (1.5c2)

DHCP Server: Only match the ClientID if the ClientID field is specified at the server, otherwise try to match the 'chaddr' (client hardware MAC address). This allows the server administrator to override whether the ClientID field (which the user can change) will be used.

DHCP Server: Ignore leading null byte of ClientID inserted by many clients so names entered in the Static Config pane will match names entered in the TCP/IP control panel.

DHCP Server: Add log messages to indicate why a static config address could not be used.

Restructured the logging function to write out status messages to a log file as well as displaying them in the Log Window. The default log file is named "IPNR.log" in the Preferences Folder.

Aug 2, 1999 (1.4c19)

DHCP: Several bug fixes: (1) Use time on existing lease if any for Discover/Request sequence or Request from client in INIT-REBOOT state; (2) Extend lease time if client is RENEWING or REBINDING even if client doesn't explicitly request more time; (3) Send NACK in response to verify (Request from client in INIT-REBOOT) if requested address is not valid for this network; (4) Allow static configs to override existing lease assignments; (5) Do not send address time option for DHCP inform; (6) Reclaim Client_ID lease bindings for IP addresses that are no longer in the dynamic pool so these clients will get a new valid lease; (7) Added delete button to DHCP Status pane to manually remove old lease bindings.

Filter Window: Changed "pass" filter action to ignore datagrams that don't match since it is easy to block such datagrams with other filters. This allows pass filters to open holes in a set of "block" filters without blocking datagrams that don't match any filter.

Perform this operation at application startup before opening any endpoints since it may rebuild the TCP/IP configuration (pressing Option during startup will force the stack to rebuild).

General: always terminate threads the same way to avoid a possible race condition when quiting the application while PPP is connected.

General: make version number and version strings more consistent.

General: Fix PowerPlant LInterruptSafeList to work with future MacOS version.

DHCP Server: save and restore "Use Verbose Logging" checkbox.

DHCP Server: fix possible freeze when saving.

ARP Window: fix bug in initial data displayed.
