This section provides tips and guidelines for monitoring the functionality of Novell BorderManager 3.9 Network Address Translation on your server.
To monitor NAT functionality, verify the following:
To see if TCP/IP routing and connectivity is established: Test IP connectivity using the LOAD PING command at the server console.
To see if NAT is enabled on the public interface: Check whether NAT is enabled in inetcfg.
To see if TCP/IP is bound to more than one interface: You can check the bindings in inetcfg.
To see if Filters are not blocking outgoing packets: You can verify the configured filters using filtcfg.
Verify the entries in the Static NAT Table are correct.
Load tcpip.nlm, then issue the SET TCP IP DEBUG=1 command:
The NAT server is receiving incoming packets.
The correct address translation is performed.
Discarded packets are not displayed on the console screen.
The connection is not being reset by the NAT router.
TCP reset packets (RSTs) are not displayed on LAN traces.
