Troubleshooting
107
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.
Problems dialing
Remote router won’t dial
• Verify that it has a default IP route or a default bridge.
• Check that the remote router is not disabled or in Dial-Back only and
has a phone number.
• It may not be in standby due to ISDN problems.
• Verify if it is in standby mode.
