symptom

Users are not able to resolve names using ISP's DNS server

Clients cannot browse the Internet

No one can ping beyond ISP's local WAN interface

cause

Most ISPs do not propagate RIP packets over their WAN links. With a default route associated to the WAN interface, all IP packets bound for networks that the NIAS or MPR server does not specifically know about are forwarded to the ISP.

fix

The methods for setting up an IP default route over a WAN link are different for NIAS 4.1, NIAS 4, and MPR 3.1 than they are for MPR 3.0.

NOTE: For a LAN only Static Route, not a WAN link on the server at all, see How To Configure a Default Route for configuration information.

MPR 3.0 ONLY:

1. Load INETCFG
2. Select Protocols-->TCP/IP
3. Enable Static Routing
4. Hit enter on Static Routing Table, then INS for a new entry
5. Under Route to Network of Host, select Default Route
6. For Next Hop Type, select WAN Call Destination
7. For Next Hop Router on Route, select the appropriate WAN Call Destination
8. Escape out and save changes
9. Down and restart the server

For NIAS 4.1, NIAS 4, and MPR 3.1 ONLY

1. Load INETCFG
2. Select Bindings, and then hit enter on the specific WAN interface binding
Important: DO NOT set up the default route under the Protocols-->TCP/IP option as with MPR 3.0. With MPR 3.1, the Static Route settings under Protocols are for LAN destinations only.
3. Hit enter on WAN Call Destinations, select the appropriate entry, or hit INS for a new entry
4. Enter or verify the WAN Call Destination
5. Select Static Routing Table and hit INS for a new entry
6. For Route to Network or Host, specify Network
7. For IP Address of Network/Host, enter 0.0.0.0. This denotes a default route
8. Do not specify a Subnetwork Mask
9. Escape out and save changes
10. Do "reinitialize system" or Down and restart the server

Enter the console command "reinitialize system" to push the new default route onto the routing table. In the event that the new default route does not appear in the routing table, i.e., TCPCON does not show it, then you may need to down the server and bring it back up. If the server cannot be "downed", then you will need to unload TCPIP, and then perform a "reinitialize system." Many times, there are processes that are depending or running on TCPIP and therefore, TCPIP cannot be unloaded until these process are stopped or unloaded. The new default route will be placed in the routing table each time the server is started.

Once the default route is set up, you can verify it under the TCPCON utility. Load TCPCON and select IP Routing Table. Hit enter on Proceed. You should see an entry that looks like this:

Destination Next Hop Type Cost Interface
default Unspecified remote 1 #
