If TCP/IP routing
•
Check that TCP/IP Routing has been set on and is enabled at the
remote end.
•
Check that the IP address of the LAN beyond the remote router is
correct, as well as the associated subnet mask.
•
If the remote router WAN IP address and subnet mask are required,
check that they have been specified correctly.
•
Check that, if required, the source and remote WAN IP addresses are
on the subnetwork.
•
Check that you have seeded the routing table with a route or a
default route, if RIP is not allowed to flow on the WAN link.
•
Be sure to reboot if you have made any IP address, control or
protocol option changes.
If IPX routing
•
Check that IPX Routing has been set on and the remote end is
enabled for IPX routing.
•
Validate that the IPX WAN network number matches the remote
router’s WAN network number.
•
Check that the IPX Routes (network numbers, hops, and ticks)
seeded into the routing table for network segments and servers
beyond the remote router are correct.
•
Check that IPX SAPs correctly identify the servers and applications
on the remote network and have valid network numbers, node
numbers, etc.
