mode. Set switches 5 and 6 up and turn the power off and then on again.
Problems Accessing the Remote Network
Bridging
¥ Make sure to reboot if you have made any bridging destination or control changes.
¥ All IP addresses must be in the same IP subnetwork (IP is being bridged).
¥ Check that a bridging default destination has been configured and is enabled.
¥ Be sure to reboot if the bridging destination or status has been changed.
¥ Check that bridging is enabled locally (use the remote listBridge command, page 272).
¥ Verify that bridging is enabled by the remote router (use the remote list command, page 271).
¥ Verify that the authentication passwords are correct.
¥ Reboot your PC if you have Windows for WorkGroups.
¥ In Windows 95, do not forget to declare shared disk directories. Check the sharing properties on your C:
drive.
¥ In the Terminal Window, check that calls are answered from the remote router.
¥ Check also for any PAP/CHAP errors for the remote router.
TCP/IP Routing
¥ Check that Ethernet LAN TCP/IP Routing has been enabled (eth list command, page 248).
¥ The IP addresses of the local and remote networks belong to different IP subnetworks.
¥ Make sure that there is an existing route to the remote network.
¥ Make sure that there is a route back from the remote network.
¥ There must be a source WAN IP address defined if you are using NAT.
¥ Check that, if required, the source and remote WAN IP addresses are on the same subnetwork
¥ Reboot if you have made any IP address or control or protocol option changes.
¥ Check that the IP address of the station/network connected to 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 a default route has been specified, if needed.
¥ Be sure to reboot if IP addresses or control or protocol option changes have been made.
¥ Check that you are using an Ethernet cable.
¥ Check that IP routing is enabled at both ends.
