172.16.2.101). With IPX, the same scenario applies. If the far
end has an IPX address of 1111:1111, the near end router
should also have an IPX network address of 1111:1111.
C. Verify in the IP routing table that an entry to the network you
are trying to reach is present and associated with the correct
port (ETH0 or WAN0).
D. Try to PING the far end router's IP address with the L128T S/
T's PING utility to verify connection.
F. Verify that the host IP network addresses agree with the local
router's Ethernet port IP address.
G. From a host machine, try to PING the far end IP address. If un-
successful, perform a trace route operation and see where the
ICMP request stopped.
7. Layer 3: General IPX Routing Troubleshooting Tips
A. Check to see that IP Routing is enabled on both the LAN and
the WAN (connection list) of the L128T S/T.
B. Make sure that the IPX network numbers are different from
the network numbers on the peer router. For instance, if the
far end has an IPX address of 1111:1111, the near end router
should have a different IPX network address (e.g., 2222.2222).
C. Verify in the IPX routing table that an entry to the network
you are trying to reach is present and associated with the cor-
rect port (ETH0 or WAN0).
D. Verify in the IPX SAP table that an entry to the server you are
trying to reach is present and associated with the correct port
(ETH0 or WAN0).
